2.5 MHz, Fixed-Output, Synchronous Tiny Boost® Regulator

Favorite

Overview

The FAN48618 is a low-power boost regulator designed to provide a minimum voltage regulated rail from a standard single-cell Li-Ion battery and advanced battery chemistries. Even below the minimum system battery voltage, the device maintains output voltage regulation. The combination of built-in power transistors, synchronous rectification, and low supply current suit the FAN48618 for battery-powered applications.
The FAN48618 is available in a 9-bump, 0.4 mm pitch, Wafer-Level Chip-Scale Package (WLCSP).

  • USB OTG Supply
  • USB Type-C VCONN Supply
  • Smart Phone, Tablets, Portable Devices and Wearables
  • Input Voltage Range: 2.7 V to 4.8 V
  • Output Voltage: 5.25 V
