PWM Control 2A Step-Down Converter

BM1513-H

FEATURES

GENERAL DESCRIPTION

Input voltage: 3.6V to +20V

Output voltage: 0.8V to VCC.

BM1513 is 2A

Oscillation frequency: 400KHz

Soft-start, Current limit, Enable function

Thermal Shutdown function

Built-in internal SW P-channel MOS

replace AP151x series

BM1513 consists of step-down switching

regulator with PWM control. These devices

include a reference voltage source, oscillation

circuit, error amplifier, internal PMOS and etc.

BM1513/A provides low-ripple power, high efficiency

and excellent transient characteristics. The PWM

control circuit is able to very 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 prevent s 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 400KHz to 60KHz.

Also, an internal compensation block is built in to

minimum external component count.

SOP-8L Pb-Free Package.

APPLICATIONS

portable DVD

LCD Monitor

Graphic Card

DVD-Video Player

Telecom Equipment

ADSL Modem

Printer and other Peripheral Equipment

Microprocessor core supply

Networking power supply

These ICs can function as step-down switching

regulators. They serve as ideal power supply units

for portable devices when coupled with the SOP-8L

mini-package, providing such outstanding features

as low current consumption. Since this converter

can accommodate an input voltage of up to 18V, it

is also ideal when operating via an AC adapter.
