■TYPICAL APPLICATION CIRCUIT

< Low ESR Capacitors >

With the XC6204/05 series, a stable output voltage is achievable even if used with a low ESR capacitor 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 1

μF. Also, please connect an input capacitor (CIN) of 0.1μF between the VIN pin and the

VSS pin in order to ensure a stable power input.

■OPERATIONAL EXPLANATION

Output voltage control with the XC6204/6205 series:

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. Further, the IC's internal circuitry can be

shutdown via the CE pin's signal.
