AP3403中文资料buck-converter数据手册Diodes规格书

描述 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.

\t 

\tThe AP3403 employs complete protection to ensure system security, including input Under Voltage Lock Out, Over Temperature Protection and hiccup mode Short Circuit Protection.

\t 

\tThis IC is available in U-DFN1616-6 package.
