☆GreenOperation-Compatible

■GENERAL DESCRIPTION

The XC6207 series are precise, low noise, high speed, and low dropout regulators with green operation (GO) function. They are

fabricated using Torex’s CMOS process. Performance features of the series include high ripple rejection and low dropout

voltage, and the series include a reference voltage source, an error amplifier, a current limiter, and a phase compensation

circuit. Output voltage is selectable in 0.05V increments within a range of 1.2V~5.0V, using laser trimming technologies. The

series' output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. GO provides high speed

operation, low power consumption and high efficiencies by automatically switching between a high speed mode (HS) and a

power save mode (PS) depending upon the load current level. The switching point of the GO to the output current is being

fixed inside the IC. The IC operates when the GO pin is low-level. When only high-speed operation is required, it can be fixed

by inputting a high level signal to the GO pin, thus providing operating conditions with the most suitable level of supply current

for the application. The CE function enables the output to be turned off resulting in greatly reduced power consumption. In

this state, with the XC6207B series, the IC turns on the internal switch located between the VOUT and VSS pins. This short

enables the electric charge at the output capacitor (CL) to be discharged via the internal auto-discharge resistance, and as a

result the VOUT pin quickly returns to the VSS level. The constant current limit circuit and the current limiter's foldback circuit

also operate as a short circuit protection for the output current limiter and the output pin.

* 2: VOUT(T) = Specified output voltage

* 3: VOUT(E) = Effective output voltage

(I.e. the output voltage when an amply stabilized "VOUT(T)＋1.0V" is provided at the VIN pin while maintaining a certain IOUT value.)

High Speed (HS) mode: The voltage of VGOH or more is input to the GO pin, or the voltage of VGOL or less is input to the GO pin

when the output current is IGO or more.

Power Save (PS) mode: The voltage of VGOL or less is input to the GO pin when the output current is IGOR or less.

* 4: Vdif={VIN1^(*6)-VOUT1^(*5)

}

* 5: VOUT1=A voltage equal to 98% of the output voltage whenever an amply stabilized IOUT {VOUT(T)+1.0V} is input in the HS mode.

* 6: VIN1=The input voltage when VOUT1 appears as Input Voltage is gradually decreased.

* 7: With the GO pin input voltage, the fixed HS mode or Green Operation (GO) is selectable.

* 8: For the XC6207B series only. The XC6207A series discharges by resistors R1 and R2 only as shown in the block diagrams.

XC6207

Series

■OPERATIONAL EXPLANATION

The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The

P-channel MOSFET, which is connected to the VOUT pin, is then driven by the subsequent output signal. The output

voltage at the VOUT pin is controlled & stabilized by a system of negative feedback. The current limit circuit and short

protect circuit operate in relation to the level of output current. The GO function monitors the output current and switches

a supply current to two values according to the level of output current. Further, the IC's internal circuitry can be shutdown

via the CE pin's signal.

XC6207 series can be set as a fixed high-speed mode or a green operation (GO) mode via a signal to the green operation

(GO) pin. Under the condition that the output current becomes IGOR or less, the IC operates in the high speed mode (HS)

when the GO pin is at high level and the IC operates in the power save (PS) mode when the GO pin is at low level. The

GO mode enables the IC to switch automatically the supply current to the high speed (HS) mode or the power save (PS)

mode according to the level of output current. While having both high-speed operation and low supply current state, the

XC6207 series can acquire high efficiency. At the HS/PS automatic switching mode (GO mode), the switching point of

the HS mode and the PS mode is being fixed inside the IC. When the output current becomes IGOR 0.3mA (TYP.) or

below, the mode changes automatically to the PS mode after the delay time of hundreds μs, and it can reduce supply

current in light load. For applications, most of portable equipment control the system current, which is the output current

to the IC, according to the system condition. Furthermore, the high-speed operation might be required. In such a case,

the mode will automatically switch to the HS mode at the automatic switching mode (GO mode), when the output current

becomes IGO or more. In the HS mode, the response of the output voltage during the output current fluctuation is better

than the PS mode. Automatic switching PS mode to HS mode causes the switching delay time of tens of μs, the output

voltage drops more than in the fixed HS mode. If the GO pin voltage is at high level (tens of μs (ΔT) before the output

current fluctuation occurs) and the IC is used in the HS mode, the output current fluctuation will be suppressed to as low as

the fixed HS mode. (cf. the following item: Load Transient Response by Switching Mode with GO pin.)

The output current at the HS/PS mode should be adjusted to 2.0mA or more / 0.3mA or less respectively when the IC is

used in the HS/PS automatic switching mode (GO mode).

It is suggested that you use this IC with either a VIN voltage or a VSS voltage input at the GO pin. If this IC is used with the

correct specifications for the GO pin, the IC will operate normally. However, supply current may increase as a result of

through current in the IC's internal circuitry when medium voltage is input.

With the XC6207 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase

compensation circuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that an

output capacitor (CL) is connected as close as possible to the output pin (VOUT) and the VSS pin. Please use an output

capacitor with a capacitance value of at least 1μF when the setting output voltage (VOUT(T)) is less than or equal to 1.8V.

Also, when the setting output voltage (VOUT(T)) is less than or equal to 2.5V, please connect an input capacitor (CIN) of

2.2μF between the VIN pin and the VSS pin in order to ensure a stable power input. The capacitor is possible to

decrease depends on bias and temperature. Therefore the phase compensation cannot be ensured effectiveness.

Stable phase compensation may not be ensured if the capacitor runs out capacitance when depending on bias and

temperature. In case the capacitor depends on the bias and temperature, please make sure the capacitor can ensure

the actual capacitance.

■OPERATIONAL EXPLANATION (Continued)

XC6207B series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the CE pin,

which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VOUT pin

and the VSS pin (cf. BLOCK DIAGRAM). In this state, the application is protected from a glitch operation caused by the

electric charge at the output capacitor (CL). The CL auto- discharge resistance at this time depends on the input

voltage. Moreover, discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the

output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R] and an output capacitor value

(CL) as τ(τ=C x R), the output voltage after discharge via the N channel transistor is calculated by the following

formulas.

V = VOUT x e ^–t/

11/33

XC6207Series

■OPERATIONAL EXPLANATION (Continued)

The XC6207 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations

of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter

circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates and

output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA

flows.

The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6207 series. In shutdown mode,

output at the VOUT pin will be pulled down to the VSS level via R1 & R2. However, as for the XC6207B series, the CL

auto-discharge resistor is connected in parallel to R1 and R2 while the power supply is applied to the VIN pin.

Therefore, time until the VOUT pin reaches the VSS level becomes short. We suggest that you use this IC with either a

VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the IC will

operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry when

medium voltage is input.

■NOTES ON USE

1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be

exceeded.

2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output

current. Please strengthen VIN and VSS wiring in particular.

3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
