FAN5601MP13X

Voltage Regulators - DC DC Switching Regulators Overview

The FAN5601MP13X is a universal step-up/step-down charge pump regulated DC/DC converter manufactured by Fairchild Semiconductor. It operates within an input voltage range of 2.7V to 5.5V and delivers up to 100mA output current at a nominal 4.5V output when powered by a 3.6V input. The device features low-noise constant-frequency operation under heavy loads and high-efficiency pulse-skip mode during light load conditions. It supports multiple switch configurations including 1:3, 1:2, 2:3, 1:1, 3:2, 2:1, and 3:1 ratios. Packaged in an 8-pin HVSON format, it achieves peak efficiency of 92% with ±3% output voltage accuracy.
