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

Favorite

Overview

The FAN48611 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 chemistry. 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 FAN48611 for battery-powered applications.
The FAN48611 is available in a 9-bump, 0.4 mm pitch, Wafer-Level Chip-Scale Package (WLCSP).

  • Input Voltage Range: 2.7 V to 4.8 V
  • Output Voltage: 5.25 V
  • 350 mA Maximum Output Current
  • Internal Synchronous Rectification
  • True Load Disconnect
  • Short-Circuit Protection
  • 9-Bump, 1.215 mm x 1.215 mm, 0.4 mm Pitch,WLCSP
  • Three External Components: 2012 1 H Inductor, 0402 Case Size Input / Output Capacitors
