Overview
Data Sheet 2A 420kHz PWM BUCK DC-DC CONVERTER AP3005 General Description The AP3005 is a 420kHz fixed frequency PWM buck (step-down) DC-DC converter, capable of driving a 2A load with high efficiency, low ripple and excellent line and load regulation.
The device includes a voltage reference, an oscillation circuit, an error amplifier, an internal PMOS and etc.
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%.
The enable function, over current protection function, short circuit protection function and soft-start function are built inside.
When OCP or SCP happens, the operation frequency will be reduced from 420kHz to 40kHz.
An internal compensation block is ...
