FAN5099 — Wide Frequency Synchronous Buck PWM

& LDO Controller

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 FAN5099 combines a high-efficiency pulse-width

modulated (PWM) controller and an LDO (low drop out)

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 low-side MOSFET’s R_DS(ON)to

sense current. In addition, the capability to operate at low

switching frequencies provides opportunities to boost

power supply efficiency by reducing switching losses and

gain cost savings using low-cost materials, such as pow-

dered iron cores, on the output inductor.

– 5V

– Shunt Regulator for 12V Operation

■ Support for Ceramic Cap on PWM Output

■ Programmable Current Limit for PWM Output

■ Wide Programmable Switching Frequency Range

(50kHz to 600kHz)

■ 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

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.

Applications

■ High-Efficiency (80+) Computer Power Supplies

■ PC/Server Motherboard Peripherals

The FAN5099’s ability to handle wide input voltage

ranges makes this controller suitable for power solutions

in a wide range of applications involving conversion input

voltages from Silver box, battery, and adapters. The

PWM regulator employs a summing-current-mode con-

trol with external compensation to achieve fast load tran-

sient response and provide system design optimization.

– 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

■ High-Power DC-to-DC Converters

FAN5099 is offered in both industrial temperature grade

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

grade (-10°C to +85°C).
