AP3203 Description
The AP3203 is a 380kHz fixed frequency, current mode, PWM buck (step-down) DC-DC converter, capable of driving a 3A load with high efficiency, excellent line and load regulation. The device integrates N-channel power MOSFET switch with low on-resistance. The current mode control provides fast transient response and cycle-by-cycle current limit.
