XC6222Series

ETR0344-007

700mA High Speed LDO Regulator

■GENERAL DESCRIPTION

The XC6222 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed

voltage regulator. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a thermal

protection circuit, and a phase compensation circuit.

The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin. In this

stand-by mode, the electric charge at the output capacitor (CL) will be discharged by the internal auto-discharge switch, and as

a result the VOUT pin will quickly return to the VSS level.

Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output

current reaches the current limit level or junction temperature reaches the temperature limit.

■PIN CONFIGURATION

*The dissipation pad for the USP-6C package should be solder-plated in recommended mount

pattern and metal masking so as to enhance mounting strength and heat release. If the pad needs

to be connected to other pins, it should be connected to the V_SS(No. 5) pin.

■ELECTRICAL CHARACTERISTICS (Continued)

NOTE:

* 1: Unless otherwise stated, input voltage is V_IN=V_OUT(T)＋1.0V.

* 2: V_{OUT (E)}is effective output voltage (Refer to the voltage chart E-0 and E-1)

It is defined as output voltages when an amply stabilized V_OUT(T)＋1.0V is supplied to the V_INpin while maintaining a certain I_OUT

* 3: The relation between V_{OU T (E)}and V_{OUT (T)}is shown in the voltage chart E-0 and E-1.

* 4: V_{OUT (T)}is nominal output voltage

.

* 5: Vdif = {V_IN1-V_OUT1

}

V

_OUT1equals 98% of the output voltage when amply stabilized V_{OUT (T)}+1.0V are supplied to the V_INpin.

_IN1is the input voltage when V_OUT1appears at the V_OUTpin while input voltage is gradually decreased.

* 6: Reverse current (I_REV) flows from V_OUTto V_IN.

* 7: V_OUTpin sink current (I_REVS) flows from V_OUTto V_SS

.

* 8: For the XC6222A/C series only. In the XC6222B/D series, the current flows from the V_OUTpin to the V_SSpin via the internal switch

when CE pin is low. Please do not connect another power supply to the V_OUTpin. Please also note when the XC6222A/C series

connects external power supply to the V_OUTpin, please use it within the range from V_OUT(E)(actual output voltage value)or more to 6.0V

or less. When the voltage less than V_OUT(E)is applied to the V_OUTpin by adding a power supply or battery, a low level signal should be

input to the CE pin for chip disable in order to protect a reverse current at V_IN< V_OUT

.

* 9: For the XC6222B/D series only. The XC6222A/C series discharges via two resistors R1 and R2 shown in the block diagram.

XC6222 Series

■OPERATIONAL EXPLANATION

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

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

pin is controlled and stabilized by a system of negative feedback. The current limit and short protection operate in relation to

the level of output current. The thermal protection operates in relation to the level of heat generation. The reverse current

protection operates when V_OUTvoltage is higher than V_INvoltage. Further, the IC's internal circuitry can be turned off via the CE

pin's signal.

XC6222Aseries

The XC6222 needs an output capacitor C_Lfor phase compensation. Values required for the phase compensation are shown in

the chart below. If a loss of the capacitance happens, stable phase compensation may not be obtained. Please ensure to

use a capacitor which does not depend on bias or temperature too much. For a stable power input, please connect an input

capacitor CIN of 1.0μF between the VIN pin and the VSS pin.

C_L=4.7μF (MIN.)

The XC6222 series includes reverse current protection to prevent the damage to any connected products such as batteries as a

result of current flow from the V_OUTpin to the V_INpin. When V_INis smaller than V_OUT,the reverse current protection works and

suppress the reverse current to 1.5μA (MAX.). When V_INis smaller then V_OUT, the V_OUTpin sink current flows from the V_OUT

pin to the V_SSpin is 95μA (TYP.) as the IC operation current. With the XC6222A/C series, when a low level signal is inputted

to the CE pin, the sink current of the V_OUTpin is minimized to 2.8μA (TYP.). However, with the XC6222B/D series, when a low

level signal is inputted to the CE pin, the sink current of the V_OUTpin goes through the C_Lauto discharge circuit to the V_SSpin

which may result in the IC being damaged. In this case, please do not connect a power supply to the V_OUTpin.

Please also note when the XC6222A/C series connects external power supply to the V_OUTpin, please use it within the range

from V_OUT(E)(actual output voltage value)or more to 6.0V or less. When the voltage less than V_OUT(E)is applied to the V_OUTpin by

adding a power supply or battery, a low level signal should be input to the CE pin for chip disable in order to protect a reverse

current at V_IN< V_OUT

.

Example) The voltage less than V_OUT(E)(actual output voltage value) is applied to the V_OUTpin as "OR" connection.

* When the CE pin is connected to the V_INpin, an output voltage 2.8V

from the step-up DC/DC goes through to the V_INpin as reverse

current up to around 150mA if the USB connection is removed from

the V_INpin (V_IN< V_OUT). CE pin voltage should be maintained low

when the USB connection is removed from the V_INpin.

XC6222

Series

■OPERATIONAL EXPLANATION (Continued)

The XC6222 series’ fold-back circuit operates as an output current limiter and a short protection circuit for the output pin.

When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When

the output pin is short-circuited to the VSS pin, the current is decreased to a level of 55mA.

When the junction temperature of the built-in driver transistor reaches the temperature limit level (150℃ TYP.), the thermal

shutdown circuit operates and the driver transistor will be turned OFF. The IC resumes its operation when the thermal

shutdown function is released and the IC’s operation is automatically restored because the junction temperature drops to the

level of 125℃ (TYP.) as the thermal shutdown release voltage.

<C_LAuto-Discharge Function>

XC6222B/D series can discharge the electric charge stored in the output capacitor (CL), when a low signal to the CE pin, which

enables the whole IC circuit to be turned off, is inputted via the N-channel transistor located between the VOUT pin and the VSS

pin (cf. BLOCK DIAGRAM). The CL auto-discharge resistance value is set at 530Ω(TYP.). The discharge time of the output

capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting the time constant of the

CL auto-discharge resistance value [R_DCHG] and the output capacitor value (CL) as τ(τ=C x R_DCHG), the output voltage after

discharge via the N-channel transistor is calculated by the following formula.

V = VOUT(E) x e ^–t/

,

or t=τIn ( V / VOUT(E) )

τ

where

V: Output voltage after discharge

VOUT (E): Output voltage

t: Discharge time

τ: CL auto-discharge resistance R_DCHG×Output capacitor (CL) value C)

The entire XC6222 circuitry can be turned off via the CE pin signal. In shutdown mode, output at the VOUT pin will be pulled

down to the VSS level via R1 & R2. However, with the XC6222B 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 is shorter.

For the XC6222A/B series, the output voltage becomes unstable, when the CE pin is left open. If this CE pin voltage is set with

the specified voltage range, the logic is fixed and the IC will operate normally. However, the supply current may increase as a

result of shoot-through current in the IC's internal circuitry when a medium voltage is input to the CE pin. With the XC6222C/D

series, when the CE pin is left open, output voltage is fixed to V_SSlevel.

■NOTES ON USE

1. For temporary, transitional voltage drop or voltage rising phenomenon, 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 wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.

3. 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.
