This Anachip version datasheet is replaced

See Diodes Datasheet for TO263-5L package

with Diodes Inc. datasheet AP1512/A

AP1512/A

50KHz, 2A/3A PWM Buck DC/DC Converter

Features

General Description

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

output version

The AP1512/A is a monolithic IC that design for a

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

driving a 2A (3A for AP1512A) 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

- Adjustable version output voltage range, 1.23V to

37V+4%

- 50KHz +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 60V

- Output load current: 2A (for AP1512)

3A (for AP1512A)

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 AP1512/A operates at a

switching frequency of 50KHz 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.

- Low power standby mode

- Built-in switching transistor on chip

- TO220-5L, TO220-5L(R) and TO263-5L Pb-free

packages

Applications

- Simple High-efficiency step-down regulator

- On-card switching regulators

- Positive to negative converter
