TOREX XC6415_1

XC6415 Series
ETR0332-005
Dual LDO Regulators with ON/OFF Switch
■GENERAL DESCRIPTION
XC6415 series are highly accurate, Dual, low noise, CMOS LDO voltage regulators. Performance features of the series include
low output noise, high ripple rejection rate, and low dropout. Extremely dense power supply circuit can be organized with a 2
channeled high speed voltage regulator in low ON resistance which is built-in to an ultra small USP-6C package. The output
voltage for each regulator is set independently by laser trimming and selectable in 0.05V increments within a range of 0.8 to 5.0V.
The EN function allows the output of each regulator to be turned off independently. In this state, with the XC6415 series, the IC
turns on the internal switch located between the VOUT and the 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 series’ output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. The high level of
output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance.
Because regulator 1 and 2 are completely isolated, a cross talk between each channel, which causes a problem during load
fluctuations, can be greatly reduced

*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, if should be connected to the VSS (No. 4) pin.

NOTE:
*1) Unless otherwise stated, VIN=VOUT(T) +1.0V.
*2) VOUT(E)= Effective output voltage (see the voltage chart)
(ie. The output voltage when “VOUT(T)+1.0V” is provided at the VIN pin while maintaining a certain IOUT value.
*3) Characteristics of the actual VOUT(E) by setting output voltage is shown in the voltage chart.
*4) VOUT(T): Nominal output voltage
(*7)
(*6)
*5) Vdif={VIN1 - VOUT1 }
*6) VOUT1: A voltage equal to 98% of the output voltage whenever an amply stabilized IOUT{VOUT(T)+1.0V} is input.
*7) VIN1: The input voltage when VOUT1 appears as input voltage is gradually decreased.
*8) For XC6415B, D, F, H series only.
XC6415A, C, E, G series discharge with only Rx1 and Rx2 resistors as shown in the BLOCK DIAGRAMS.
*9) Each channel is measured when the other channel is turned off (VEN=VSS).

XC6415 Series
■OPERATIONAL DESCRIPTION
<Output Voltage Control>
The voltage divided by resistors Rx1 and Rx2 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 and stabilized by a system of negative feedback. The current limit circuit and short protect circuit
operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the EN pin's signal.
< XC6415BB Series >
<CL Auto-Discharge Function>
XC6415B, D, F, H series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the EN
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). The CL discharge resistance is set to 550Ω when VIN is 6.0V (TYP.) and VOUT
is 4.0V (TYP.). 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/τ, or ｔ=τln（ VOUT(E) / V ）
( V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time,
τ: CL auto-discharge resistance R×Output capacitor (CL) value C)
CL high-speed discharge function can be set by each regulator.
<Current Limiter, Short-Circuit Protection>
The XC6415 series includes a fold-back circuit, which aid the operations of the current limiter and circuit protection. When
the load current reaches the current limit level, the fold-back circuit operates and output voltage drops. As a result of this
drop in output voltage, output current also decreases. When the output pin is shorted, a current of about 20mA flows.
<EN Pin>
The IC's internal circuitry can be shutdown via the signal from the EN pin with the XC6415 series. In shutdown mode,
output at the VOUT pin will be pulled down to the VSS level via Rx1 & Rx2. However, as for the XC6415B, D, F, H series,
the CL auto-discharge resistor is connected in parallel to Rx1 and Rx2 while the power supply is applied to the VIN pin.
Therefore, time until the VOUT pin reaches the VSS level becomes short. The EN pin is CMOS input, but in case the EN
pin with pulled down resistor, the EN input current will be increase when the IC operates. Also, in case of the EN pin
without pulled down resistor, the output voltage becomes unstable when the EN pin is left open. If this IC is used with the
correct output voltage for the EN pin, the logic is fixed and 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 wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
