A Product Line of Diodes Incorporated AP3409/A 3A, 4MHz HIGH EFFICIENCY SYNCHRONOUS BUCK CONVERTER Description Pin Assignments The AP3409/A is a current mode, PWM synchronous buck DC/DC converter, capable of driving a 3A load with high efficiency, excellent line and load regulation. It operates in continuous PWM mode. The AP3409/A integrates synchronous P-channel and N-channel power MOSFET switches with low on-resistance. It is ideal for portable applications powered from a single Li-ion battery. 100% duty cycle and low on-resistance P-channel internal power MOSFET can maximize the battery life. The switching frequency of AP3409/A can be programmable from 300kHz to 4MHz, which allows small-sized components, such as capacitors and inductors.
