XCL210Series

ETR28009-005a

50mA/200mA Inductor Built-in Step-Down “micro DC/DC” Converters

☆Green Operation Compatible

■GENERAL DESCRIPTION

The XCL210 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one

tiny package (2.0mm×2.5mm, h=1.0mm). An internal coil simplifies the circuit and enables minimization of noise and other

operational trouble due to the circuit wiring. A wide operating voltage range of 2.0V to 6.0V enables support for applications that

require an internally fixed output voltage from 1.0V to 4.0V in increments of 0.05V.

During stand-by, all circuits are shutdown to reduce current consumption to as low as 0.1μA or less.

With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel MOS driver transistor is forced OFF when

input voltage becomes UVLO detect Voltage or lower.

The XCL210 integrate CL discharge function which enables the electric charge at the output capacitor CL to be discharged via

the internal discharge switch located between the LX and VSS pins. When the devices enter stand-by mode, output voltage

quickly returns to the VSS level as a result of this function.

An ultra-low quiescent current circuit and synchronous rectification enable a significant reduction of dissipation in the IC, and the

IC operates with high efficiency at both light loads and heavy loads. Current limit PFM is used for the control method, and even

when switching current superposition occurs, increases of output voltage ripple are suppressed, allowing use over a wide voltage

and current range. The IC is compatible with low-capacitance ceramic capacitors, and a small, high-performance step-down DC-

DC converter can be created.

The actual output voltage V_OUT(E)in the electrical characteristics is the threshold voltage of the PFM comparator in the block

diagram. Therefore the average output voltage of the step-down circuit, including peripheral components, depends on the ripple

voltage. Before use, test fully using the actual device.

■OPERATIONAL EXPLANATION (Continued)

(1) The feedback voltage (FB voltage) is the voltage that results from dividing the output voltage with the IC internal dividing

resistors R_FB1and R_FB2. The PFM comparator compares this FB voltage to V_REF. When the FB voltage is lower than V_REF, the PFM

comparator sends a signal to the buffer driver through the PFM control circuit to turn on the Pch driver Tr. When the FB voltage is

higher than V_REF, the PFM comparator sends a signal to prevent the Pch driver Tr from turning on.

(2) When the Pch driver Tr is on, the current sense circuit monitors the current that flows through the Pch driver Tr connected to the

Lx pin. When the current reaches the set PFM switching current (I_PFM), the current sense circuit sends a signal to the buffer driver

through the PFM control circuit. This signal turns off the Pch driver Tr and turns on the Nch synchronous rectification switch Tr.

(3) The on time (off time) of the Nch synchronous rectification switch Tr is dynamically optimized inside the IC. After the off time

elapses and the PFM comparator detects that the V_OUTvoltage is higher than the set voltage, the PFM comparator sends a signal

to the PFM control circuit that prevents the Pch driver Tr from turning on. However, if the V_OUTvoltage is lower than the set voltage,

the PFM comparator starts Pch driver Tr on.

By continuously adjusting the interval of the linked operation of (1), (2) and (3) above in response to the load current, the output

voltage is stabilized with high efficiency from light loads to heavy loads.

The PFM switching current monitors the current that flows through the Pch driver Tr, and is a value that limits the Pch driver Tr

current. The Pch driver Tr remains on until the coil current reaches the PFM switching current (I_PFM). An approximate value for this

on-time t_ONcan be calculated using the following equation:

t_ON= L × I_PFM/ (V_IN– V_OUT

)

To avoid excessive ripple voltage in the event that the coil current does not reach the PFM switching current within a certain

interval even though the Pch driver Tr has turned on and the FB voltage is above V_REF, the Pch driver Tr can be turned off at any

timing using the maximum on-time function of the PFM control circuit. If the Pch driver Tr turns off by the maximum on-time function

instead of the current sense circuit, the Nch synchronous rectification switch Tr will not turn on and the coil current will flow to the

V_OUTpin by means of the parasite diode of the Nch synchronous rectification switch Tr.

When the V_INvoltage is lower than the output voltage, through mode automatically activates and the Pch driver Tr stays on

continuously.

(1) In through mode, when the load current is increased and the current that flows through the Pch driver Tr reaches a load current

that is several tens of mA lower than the set PFM switching current (I_PFM), the current sense circuit sends a signal through the PFM

control circuit to the buffer driver. This signal turns off the Pch driver Tr and turns on the Nch synchronous rectification switch Tr.

(2) After the on-time (off-time) of the Nch synchronous rectification switch Tr, the Pch driver Tr turns on until the current reaches

the set PFM switching current (I_PFM) again.

If the load current is large as described above, operations (1) and (2) above are repeated. If the load current is several tens of

mA lower than the PFM switching current (I_PFM), the Pch driver Tr stays on continuously.

<V_INstart mode>

When the V_INvoltage rises, V_INstart mode stops the short-circuit protection function during the interval until the FB voltage

approaches V_REF. After the V_INvoltage rises and the FB voltage approaches V_REFby step-down operation, V_INstart mode is

released. In order to prevent an excessive rush current while V_INstart mode is activated, the coil current flows to the V_OUTpin by

means of the parasitic diode of the Nch synchronous rectification Tr. In V_INstart mode as well, the coil current is limited by the

PFM switching current.

13/25

XCL210 Series

■OPERATIONAL EXPLANATION (Continued)

<Short-circuit protection function>

The short-circuit protection function monitors the V_OUTpin voltage, and if the V_OUTpin voltage drops below the Short Protection

Threshold Voltage (V_SHORT) due to a short circuit or overcurrent, the short circuit protection function operates.

When the short-circuit protection function is activated, the Pch driver Tr and Nch Synchronous Switch Tr are held off. If the V_OUT

pin voltage exceeds the Short Protection Threshold Voltage (V_SHORT) after the short-circuit protection function is activated, normal

operation resumes.

To cancel the short-circuit protection function, it is necessary to start the IC after putting the IC in the standby state with the CE

function, or to raise the input voltage after setting the input voltage below the UVLO detection voltage (V_UVLO(E)-V_HYS(E)).

When the V_INpin voltage drops below the UVLO detection voltage, the IC stops switching operation at any selected timing, turns

off the Pch driver Tr and Nch synchronous rectification switch Tr (UVLO mode). When the V_INpin voltage recovers and rises above

the UVLO release voltage, the IC restarts operation.

<C_Ldischarge function>

On the XCL210 series, a C_Ldischarge function is available as an option (Type C/D). This function enables quick discharging of

the C_Lload capacitance when “L” voltage is input into the CE pin by the Nch Tr connected between the V_OUT-GND pins, or in

UVLO mode. This prevents malfunctioning of the application in the event that a charge remains on C_Lwhen the IC is stopped.

The discharge time is determined by C_Land the C_Ldischarge resistance R_DCHG, including the Nch Tr (refer to the diagram below).

Using this time constant τ= C_L×R_DCHG, the discharge time of the output voltage is calculated by means of the equation below.

V = V_OUT× e ^{- t /}^τ, or in terms of t, t = τIn(V_OUT/ V)

■NOTE ON USE

1. Be careful not to exceed the absolute maximum ratings for externally connected components and this IC.

2. The DC/DC converter characteristics greatly depend not only on the characteristics of this IC but also on those of externally

connected components, so refer to the specifications of each component and be careful when selecting the components. Be

especially careful of the characteristics of the capacitor used for the load capacity C_Land use a capacitor with B characteristics

(JIS Standard) or an X7R/X5R (EIA Standard) ceramic capacitor.

3. Use a ground wire of sufficient strength. Ground potential fluctuation caused by the ground current during switching could cause

the IC operation to become unstable, so reinforce the area around the GND pin of the IC in particular.

4. Mount the externally connected components in the vicinity of the IC. Also use short, thick wires to reduce the wire impedance.

5. When the voltage difference between V_INand V_OUTis small, switching energy increases and there is a possibility that the ripple

voltage will be too large. Before use, test fully using the actual device.

6. The CE pin does not have an internal pull-up or pull-down, etc. Apply the prescribed voltage to the CE pin.

7. If other than the recommended inductance and capacitance values are used, excessive ripple voltage or a drop in efficiency

may result.

8. If other than the recommended inductance and capacitance values are used, a drop in output voltage when the load is excessive

may cause the short-circuit protection function to activate. Before use, test fully using the actual device.

9. At high temperature, excessive ripple voltage may occur and cause a drop in output voltage and efficiency. Before using at high

temperature, test fully using the actual device

10. At light loads or when IC operation is stopped, leakage current from the Pch driver Tr may cause the output voltage to rise.

11. The average output voltage may vary due to the effects of output voltage ripple caused by the load current. Before use, test

fully using the actual device.

12. If the C_Lcapacitance or load current is large, the output voltage rise time will lengthen when the IC is started, and coil current

overlay may occur during the interval until the output voltage reaches the set voltage (refer to the diagram below).

13. When the IC is started, the short-circuit protection function does not operate during the interval until the V_OUTvoltage reaches

a value near the set voltage.

14. If the IC is started at a V_INvoltage that activates through mode, it is possible that the short-circuit protection function will not

operate. Before use, test fully using the actual device.

15. If the load current is excessively large when the IC is started, it is possible that the V_OUTvoltage will not rise to the set voltage.

Before use, test fully using the actual device.

■NOTE ON USE (Continued)

16. In actual operation, the maximum on-time depends on the peripheral components, input voltage, and load current. Before use,

test fully using the actual device.

17. When the V_INvoltage is turned on and off continuously, excessive rush current may occur while the voltage is on. Before use,

test fully using the actual device.

18. When the V_INvoltage is high, the Pch driver may change from on to off before the coil current reaches the PFM switching

current (I_PFM), or before the maximum on-time elapses. Before use, test fully using the actual device.

19. When the IC change to the Through Mode at light load, the supply current of this IC can increase in some cases.

20. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be

exceeded.

21. Torex places an importance on improving our products and their reliability.

We request that users incorporate fail-safe designs and post-aging protection treatment when using Torex products in their

systems.

22. The UVLO function can be activated when the UVLO hysteresis width gets to about 0mV and after several tens ms elapses

at light loads.

Before use, test fully using the actual device.

23. Please use within the power dissipation range below. Please also note that the power dissipation may change by test

conditions, the power dissipation figure shown is PCB mounted.

24. The proper position of mounting is based on the coil terminal

Pd vs Operating Temperature

Package Body Temperature vs Operating Temperature

the power loss of micro DC/DC according to the following formula:

power loss = V_OUT×I_OUT×((100/EFFI) – 1) (W)

■NOTE ON USE (Continued)

●Instructions of pattern layouts

1. To suppress fluctuations in the V_INpotential, connect a bypass capacitor (C_IN) in the shortest path between the V_INpin and

ground pin.

2. Please mount each external component as close to the IC as possible.

3. Wire external components as close to the IC as possible and use thick, short connecting traces to reduce the circuit impedance.

4. Make sure that the ground traces are as thick as possible, as variations in ground potential caused by high ground currents at

the time of switching may result in instability of the IC.

5. Internal driver transistors bring on heat because of the transistor current and ON resistance of the driver transistors.

6. As precautions on mounting, please set the mounting position accuracy within 0.05 mm
