TS3553 - Taiwan Semiconductor

TS3553 3A / 350kHz Synchronous Buck DC/DC Converter

The TS3553 is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 3A continuous load current capability. Fault protection includes cycle-by-cycle current limit, input UVLO, output over voltage protection and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on. This device use.
