PWM CONTROL 5A STEP-DOWN CONVERTER

FSP3132

FEATURES

GENERAL DESCRIPTION

Input voltage: 3.6V to 23V.

FSP3132 consists of step-down switching regulator

with PWM control. These devices include a

reference voltage source, oscillation circuit, error

amplifier, internal PMOS and etc.

Output voltage: 0.8V to VCC.

Duty ratio: 0% to 100% PWM control

Oscillation frequency: 300KHz typ.

Soft-start, Current limit, Enable function

Thermal Shutdown function

FSP3132 provides low-ripple power, high efficiency,

and excellent transient characteristics. The PWM

control circuit is able to vary the duty ratio linearly

from 0 up to 100%. This converter also contains an

error amplifier circuit as well as a soft-start circuit

that prevents overshoot at startup. An enable

function, an over current protect function and a

short circuit protect function are built inside, and

when OCP or SCP happens, the operation

frequency will be reduced from 300KHz to 30KHz.

Also, an internal compensation block is built in to

minimum external component count.

Built-in internal SW P-channel MOSFET

SOP8L Package.

TYPICAL APPLICATION

PC Motherboard

LCD Monitor

Graphic Card

DVD-Video Player

Telecom Equipment

ADSL Modem

Printer and other Peripheral Equipment

Microprocessor core supply

Networking power supply

With the addition of an internal P-channel Power

MOS, a coil, capacitors, and a diode connected

externally, these ICs can function as step-down

switching regulators. They serve as ideal power

supply units for portable devices when coupled with

outstanding features as low current consumption.

Since this converter can accommodate an input

voltage up to 23V, it is also suitable for the operation

via an AC adapter.
