FAN5099 Wide Frequency Synchronous Buck PWM & LDO Controller
Features
■ General Purpose PWM Regulator and LDO Controller ■ Input
Voltage Range: 3V to 24V ■ Output
Voltage Range: 0.
8V to 15V ■ VCC
Description
The FAN5099 combines a high-efficiency pulse-width modulated (PWM) controller and an LDO (Low DropOut) linear regulator controller.
The PWM controller is designed to operate over a wide frequency range (50kHz to 600kHz) to accommodate a variety of applications.
Synchronous rectification provides high efficiency over a wide range of load currents.
Efficiency is further enhanced by using the...
