FP6329/A

Synchronous Buck PWM

DC-DC Controller

Description

Features

The FP6329/A is designed to drive two N-channel

MOSFETs in a synchronous rectified buck topology.

It provides the output adjustment, internal soft-start,

frequency compensation networks, monitoring and

protection functions into a single package.

● Operates from +5V or +12V

● High Output Current

● Drives Two Low Cost N-Channel MOSFETs

● Fast Transient Response

● Simple Single-Loop Control Design

( Voltage-Mode PWM Control)

● Internal Soft-Start

● Over-Current Protection

● Over-Voltage Protection

● Under-Voltage Protection

● SOP-8 Package

The FP6329/A operating at fixed 300/600kHz

frequency provide simple, single feedback loop,

voltage mode control with fast transient response.

The resulting PWM duty ratio ranges from 0-100%.

The FP6329/A features over current protection.

The output current is monitored by sensing the

voltage drop across the R_DS-ONof the low side

MOSFET which eliminates the need for a current

sensing resistor.

● RoHS Compliant

Applications

● Motherboard

● Graphic Card

This device is available in SOP-8 package.

● Telecomm Equipments

● High Power DC-DC Regulators

● Switching Power Supply (SPS)
