NOT RECOMMENDED FOR NEW DESIGN CONTACT US Preliminary Datasheet 1.5MHz Synchronous Step-down DC-DC Converter AP3410 Features General Description The AP3410 is a high efficiency step-down DC-DC High Efficiency Buck Power Converter voltage converter. The chip operation is optimized by Wide Input Voltage Range: 2.5V to 5.5V peak-current mode architecture with built-in Adjustable Output Voltage: 0.6V to 0.9V IN synchronous power MOSFET switchers. The Low R Internal Switches:200m (V =5V) DS(ON) IN oscillator and timing capacitors are all built-in Built-in Power Switches for Synchronous providing an internal switching frequency of 1.5MHz Rectification with High Efficiency that allows the use of small surface mount inductors Output Current: 1.2A and capacitors for portable product implementations. Feedback Voltage: 600mV 1.5MHz Constant Frequency Operation Integrated Soft Start (SS), Under Voltage Lock Out Thermal Shutdown Protection (UVLO), Thermal Shutdown Detection (TSD) and Low Dropout Operation at 100% Duty Cycle Short Circuit Protection are designed to provide No Schottky Diode Required reliable product applications. Input Over Voltage Protection Output Over Voltage Protection The device is available in adjustable output voltage Over Current Protection version ranging from 0.6V to 0.9V when input IN For automotive applications requiring specific voltage range is from 2.5V to 5.5V, and is able to change control (i.e. parts qualified to AEC- deliver up to 1.2A.
