Diodes AP3405 600mA Step-down DC-DC Converter with Synchronous Rectifier
The AP3405 is highly integrated with 2.0MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, and is capable of driving a 600mA load with high efficiency and excellent line and load regulation. The device’s high efficiency is easily configured by using external components.
Current mode control provides fast transient response and cycle-by-cycle current limit. The AP3405 employs complete protection to ensure system security, including Input Undervoltage Lockout, Overtemperature Protection and hiccup mode Short Circuit Protection.
The device is targeted at cellphone, tablet and netbook applications. AP3405 is available in the space saving, industry standard U-DFN2020-8 package.
