General Description
The TS3552 is a synchronous step-down DC/DC converter that provides wide 4.75V to 23V input voltage range
and 2A 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 uses current mode control scheme that provides fast transient response. In
shutdown mode, the regulator draws 1µA or less of supply current.
