AP1501A

150Khz, 5A PWM Buck DC/DC Converter

ꢀ Features

General Description

ꢀ

- Output voltage: 3.3V, 5V, 12V and adjustable

output version

The AP1501A series are monolithic IC that design

for a step-down DC/DC converter, and own the

ability of driving a 5A load without additional

transistor component. Due to reducing the number

of external component, the board space can be

saved easily. The external shutdown function can

be controlled by logic level and then come into

standby mode. The internal compensation makes

feedback control have good line and load regulation

without external design. Regarding protected

function, thermal shutdown is to prevent over

temperature operating from damage, and current

limit is against over current operating of the output

- Adjustable version output voltage range, 1.23V to

37V+4%

- 150Khz +15% fixed switching frequency

- Voltage mode non-synchronous PWM control

- Thermal-shutdown and current-limit protection

- ON/OFF shutdown control input

- Operating voltage can be up to 40V

- Output load current: 5A

- TO220-5L, TO220-5L(R) and TO263-5L packages

- Low power standby mode

- Built-in switching transistor on chip

switch. The AP1501A series operates at

switching frequency of 150Khz thus allowing

smaller sized filter components than what would be

needed with lower frequency switching regulators.

Other features include a guaranteed +4% tolerance

on output voltage under specified input voltage and

output load conditions, and +15% on the oscillator

frequency. The output version included fixed 3.3V,

5V, 12V, and an adjustable type. The packages are

available in a standard 5-lead TO-220 package and

a 5-lead TO-263.

ꢀ Applications

- Simple High-efficiency step-down regulator

- On-card switching regulators

- Positive to negative converter
