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/  
,
or ｔ=τln（ VOUT(E) / V ）  
τ
( 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.
