TS3553 3A/350kHz Synchronous Buck DC/DC Converter SOP-8EP Pin Definition: 1. BS 8. SS 2. VIN 7. EN 3. SW 6. COMP 4. GND 5. FB General Description 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 uses current mode control scheme that provides fast transient response. In shutdown mode, the regulator draws 1µA or less of supply current.
