Datasheet

2.5A 150KHZ PWM Buck DC/DC Converter

PJ1507

General Description

Features

The PJ1507 is a easy to use adjustable

step-down (buck) switch-mode voltage regulators.

The device is available in an adjustable output

version. It is capable of driving a 2.5A load with

excellent line and load regulation.

• Adjustable output version

• Output adjustable from 1.23v to 34V

• Fixed 150KHz frequency internal oscillator

• Guaranteed 2.5A output load current

• Input voltage range up to 36V

• Low power standby mode, I_Qtypically 70 µA

• TTL shutdown capability

Requiring

minimum number of external

components, the regulator is simple to use and

include internal frequency compensation, and a

fixed-frequency oscillator.

• Excellent line and load regulation

• High efficiency

• Thermal shutdown and current limit protection

• Available in TO252-5L package

The output voltage is guaranteed to ±3%

tolerance under specified input voltage and

output load conditions. The oscillator frequency is

guaranteed to ±15%. External shutdown is

included, featuring typically 80 µA standby current.

Self protection features include a two stage

frequency reducing current limit for the output

switch and an over temperature shutdown for

complete protection under fault conditions.

Applications

• Simple High-efficiency step-down regulator

• On-card switching regulators

• Positive to negative converter

• LCD monitor and LCD TV

• DVD recorder and PDP TV

• Battery charger

• Step-down to 3.3V for microprocessors

The PJ1507 is available in TO252-5L package.
