AP1518

300KHz, 3A PWM Buck DC/DC Converter

General Description

Features

The AP1518 series are monolithic IC designed for a

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

driving a 3A load without external transistor. 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 to prevent over current operating

of the output switch. If current limit function

occurred and V_FBis down to 0.5V below, the

switching frequency will be reduced. The AP1518

series operate at a switching frequency of 300KHz

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

packages are available in a standard 5-lead

TO-220 package or a 5-lead TO-263.

- Adjustable version output voltage range, 0.8V to

18V+4%

- 300KHz +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 22V

- Output load current: 3A

- TO220-5L and TO263-5L Pb-Free 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
