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

– V_CC

The FAN5069 combines a high-efficiency Pulse-Width-

Modulated (PWM) controller and an LDO (Low DropOut)

linear regulator controller. Synchronous rectification pro-

vides 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.

– 5V

■ Shunt Regulator for 12V Operation

■ Support for Ceramic Cap on PWM Output

■ Programmable Current Limit for PWM Output

Both the linear and PWM regulator soft-start are con-

trolled by a single external capacitor, to limit in-rush cur-

rent from the supply when the regulators are first

enabled. Current limit for PWM is also programmable.

■ Programmable Switching Frequency (200KHz to

600KHz)

The PWM regulator employs a summing-current-mode

control with external compensation to achieve fast load

transient response and provide design optimization.

■ R_DS(ON)Current Sensing

■ Internal Synchronous Boot Diode

■ Soft-Start for both PWM and LDO

■ Multi-Fault Protection with Optional Auto-restart

■ 16-pin TSSOP Package

FAN5069 is offered in both industrial temperature grade

(-40°C to +85°C) as well as commercial temperature

grade (-10°C to +85°C).

Applications

■ PC/Server Motherboard Peripherals

– V_{CC_MCH}(1.5V), V_DDQ(1.5V) and

V_{TT_GTL}(1.25V)

■ Power Supply for

– FPGA, DSP, Embedded Controllers, Graphic Card

Processor, and Communication Processors

■ Industrial Power Supplies

■ High-Power DC-to-DC Converters
