AP5004

PWM CONTROL 2.5A STEP-DOWN CONVERTER

General Description

Features

AP5004 consists of step-down switching regulator with PWM

control. These devices include a reference voltage source,

oscillation circuit, error amplifier, internal NMOS.

•

Input Voltage: 10V to 32V

Adjustable Output Voltage from 0.8V to 6V

Duty Ratio: 0% to 90% PWM control

Oscillation Frequency: 300KHz typical

Short Circuit Protect Frequency:50 KHz

2uA Maximum Standby Current

Current Limit, Enable Function

Thermal Shutdown Function

Built-in Internal SW N-channel MOS

SOP-8L: Available in “Green” Molding Compound

(No Br, Sb)

AP5004 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 90%. 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 300 KHz to 50 KHz. Also, an

internal compensation block is built to minimize external

component count.

With built-in power NMOS, a step-down switching regulator is

easy to be built by adding a coil, capacitors and a diode.

The high efficiency, low standby current, high input voltage (32V)

and output current (2.5A) combining with small SOP-8L package

give AP5004 unprecedented advantage in high power system

applications.
