AP1509

150KHz, 2A PWM BUCK DC/DC CONVERTER

General Description

Features

The AP1509 series are 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 AP1509 series operates

at a switching frequency of 150KHz thus allow 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 chips are available in a standard 8-lead

SOP-8 package.
