600mA STEP-DOWN DC/DC CONVERTER WITH SYNCHRONOUS RECTIFIER
Description
The AP3403 is a 2.0MHz fixed frequency, current mode, PWM
synchronous buck (step-down) DC-DC converter, capable of driving a
600mA load with high efficiency, excellent line and load regulation.
The high efficiency is easily configured by using an inductor, resistors
and capacitors as the external components. Current mode control
provides fast transient response and cycle-by-cycle current limit.
The AP3403 employs complete protection to ensure system security,
including input Under Voltage Lock Out, Over Temperature Protection
and hiccup mode Short Circuit Protection.
This IC is available in U-DFN1616-6 package.
