1 / 12 page  Data Sheet 1.5A, 1.4MHz High Efficiency Synchronous DC-DC Buck Converter AP3418 Aug. 2012 Rev. 1. 2 BCD Semiconductor Manufacturing Limited 1 General Description The AP3418 is a 1.4MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 1.5A load with high efficiency, excellent line and load regulation. The device integrates synchronous P-channel and N-channel power MOSFET switches with low on-resistance. It is ideal for powering portable equipment that runs from a single Li-ion battery. A standard series of inductors are available from several different manufacturers optimized for use with the AP3418. This feature greatly simplifies the design of switch-mode power supplies. The AP3418 is available in SOT-23-5 package. Features • Input Voltage Range: 2.5V to 5.5V • Output Voltage: 0.6V to VIN • ADJ Output • Fixed 1.4MHz Frequency • High Efficiency up to 95% • Output Current: 1.5A • Current Mode Control • 100% Duty Cycle in Dropout • Built-in Over Current Protection • Built-in Short Circuit Protection • Built-in Thermal Shutdown Protection • Built-in UVLO Function • Built-in Soft-start Applications • LCD TV • Set-top Box • Datacom • Portable Device • Smart Phone Figure 1.
