AP1501

150Khz, 3A PWM Buck DC/DC Converter

ꢀ Features

General Description

ꢀ

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

output version

The AP1501 series are monolithic IC that design for

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

of driving a 3A 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 switch. The AP1501

series operates at a 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.

- 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: 3A

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

- Low power standby mode

- Built-in switching transistor on chip

ꢀ Applications

- Simple High-efficiency step-down regulator

- On-card switching regulators

- Positive to negative converter
