The XC9253R series is a group of synchronous-rectification type DC/DC converters with a built-in 0.6ΩP-channel driver transistor and 0.7ΩN-channel switching transistor, designed to allow the use of ceramic capacitors. The ICs enable a high efficiency, stable power supply with an output current of 500mA to be configured using only a coil and two capacitors connected externally. Minimum operating voltage is 2.0V~6.0V. Output voltage is 3.3V(accuracy: ±2.0%). With the built-in oscillator, oscillation frequency is set to 600kHz. As for operation mode, the XC9253R series is automatic PWM/PFM switching control allowing fast response, low ripple and high efficiency.
