AP1519

300KHz, 2A PWM Buck DC/DC Converter

Features

General Description

- Adjustable version output voltage range, 0.8V to

18V+4%

The AP1519 is monolithic IC designed for a

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

driving a 2A load without additional transistor. It

saves board space. The external shutdown function

can be controlled by logic level and then come into

standby mode. The internal compensation makes

feedback control having 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. If current limit function occurs and

V_FBis down below 0.5V, the switching frequency

will be reduced. The AP1519 series operates at a

switching frequency of 300KHz thus allows 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 chips are available in a standard

8-lead SOP-8 package.

- 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: 2A

- SOP-8L 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
