FAN5069

PWM and LDO Controller Combo

Features

Description

■ General Purpose PWM Regulator and LDO Controller

■ Input Voltage Range: 3V to 24V

■ Output Voltage Range: 0.8V to 15V

■ VCC

The FAN5069 combines a high efficiency PWM controller and a

LDO (Low DropOut) linear regulator controller. Synchronous

rectification provides high efficiency over a wide range of load

currents. Efficiency is further enhanced by using the low-side

MOSFET's R_DS(ON)to sense current.

Both the linear and PWM regulator soft-start are controlled by a

single external capacitor, to limit in rush current from the supply

when the regulators are first enabled. Current limit for PWM is

also programmable.

Shunt Regulator for 12V Operation

■ Support for Ceramic Cap on PWM Output

■ Programmable Current Limit for PWM Output

■ Programmable Switching Frequency (200KHz to 600KHz)

■ R_DS(ON)Current Sensing

The PWM regulator employs a Summing-Current-Mode control

with external compensation to achieve fast load transient

response and provide system design optimization.

■ Internal Synchronous Boot Diode

■ Soft-Start for both PWM and LDO

FAN5069 is offered in both industrial temperature grade (-40°C

to +85°C) as well as commercial temperature grade (-10°C to

+85°C)

■ Multi-Fault Protection with Optional Auto-restart

■ 16-pin TSSOP Package

Applications

■ PC/Server Motherboard Peripherals

VCC_MCH (1.5V), VDDQ (1.5V) and VTT_GTL(1.25V)

■ Power Supply for

FPGA, DSP, Embedded Controllers, Graphic Card Proces-

sor, and Communication Processors

■ Industrial Power Supplies

■ High Power DC-to-DC Converters
