AP3408中文资料buck-converter数据手册Diodes规格书

描述 Description

The AP3408 is a current mode, PWM synchronous buck DC/DC converter, capable of driving a 2A load with high efficiency, excellent line and load regulation. It operates in continuous PWM mode. The AP3408 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 AP3408 can be programmable from 300kHz to 4MHz, which allows small-sized components, such as capacitors and inductors. A standard series of inductors from several different manufacturers are available. This feature greatly simplifies the design of switch-mode power supplies. The AP3408 is available in DFN-3Ω3-10 and PSOP-8 packages.
