AP1515

150KHz, 1.5A PWM Buck DC/DC Converter

Features

General Description

- Output voltage: 3.3V and adjustable output

version

The AP1515 series are monolithic IC designed for a

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

driving a 1.5A 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 switch. If current

limit function occurred and V_FBis down to 0.5V

below, the switching frequency will be reduced.

- Adjustable version output voltage range, 1.23V to

18V+4%

- 150KHz +15% fixed switching frequency

- Voltage mode non-synchronous PWM control

- Thermal-shutdown and current-limit protection

- Operating voltage can be up to 22V

- Output load current: 1.5A

- SIP-4L Pb-Free package

- Low power standby mode

- Built-in switching transistor on chip

- Very Low Cost

Applications

The AP1515 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

and an adjustable type. The packages are available

in a standard 4-lead SIP-4L package.

- Simple High-efficiency step-down regulator

- On-card switching regulators

- Positive to negative converter
