AH1403/AH1405 is a 40V/1A step-down synchronous rectifier IC developed by ZPMC, which is capable of driving up to 1A load current in a small SOT23-6 package in China. The MOSFETs are internally integrated with a very low RDS internal resistance of 10HoE metal oxide semiconductor field effect transistors. With a wide input voltage range of 6V to 40V and fixed 5V and 3.3V output voltages, they are ideal for use in non-stable power supplies in the industrial sector. 1A continuous load current output ensures stable operation in all states of the system. With an efficiency of up to 94%, it meets the increasing demand for energy efficiency and durability in all systems. The internal oscillation frequency of 100KHz ensures minimal EMI interference to the rest of the system. The chip also features soft-start and cycle-by-cycle over-current protection, short-circuit protection and over-temperature protection.
