面実装 Current-Mode PWM Step-Down DC-DC Converter IC

    AP-2403-E2 

The AP2403 is a Current-Mode Synchronous Step-Down DC-DC Converter with excellent transient response. The output voltage is selectable from the range of 0.8V to 5.0V by an external resistor. The input voltage ranges from 3.0V to 5.5V which is most suitable to generate a 1.0V, a 1.2V, and a 1.8V power supplies. Power MOSFETs are built in the AP2403; the maximum output current of the AP2403 is 2.5A. The switching frequency is selectable from 300 kHz to 4 MHz by the external resistor. For the protections, the AP2403 has Over-Current protection, Low-Input Voltage protection, Thermal protection and Power-Good function.
