APE1707

150KHz, 2A PWM BUCK DC/DC CONVERTER

FEATURES

DESCRIPTION

Output Voltage : 3.3V, 5V, 12V and Adjustable

The APE1707 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 VFB is down below 0.5V,

the switching frequency will be reduced.

Output Voltage

Adjustable Version Output Voltage Range, 1.23V

to 38.5V

150KHz Fixed Switching Frequency.

Voltage Mode Non-synchronous PWM Control.

Thermal-shutdown and Current-limit Protection.

ON/OFF Shutdown Control Input.

Short Circuit Protect(SCP)

Operating Voltage can be up to 40V

Output Load Current 2A

The APE1707 series operates at a switching frequency

of 150KHz thus allow smaller sized filter components than

what would be needed with lower frequency switching

regulators. The output version included fixed 3.3V, 5V, 12V,

and an adjustable type. The chips are available in SO-8,

ESOP-8, TO-263-5L and TO-252-5L packages.
