DescriptionThe TPS54332DDA is a 28-V, 3.5-A non-synchronous buck converter that integrates alow-RDS(on) high-side MOSFET. To increase efficiency at light loads, apulse-skipping Eco-Mode feature is automatically activated. Furthermore, the 1-μA shutdown supplycurrent allows the device to be used in battery-powered applications. Current mode control withinternal slope compensation simplifies the external compensation calculations and reduces componentcount while allowing the use of ceramic output capacitors. A resistor divider programs thehysteresis of the input undervoltage lockout. An overvoltage transient protection circuit limitsvoltage overshoots during start-up and transient conditions. A cycle-by-cycle current limit scheme,frequency foldback and thermal shutdown protect the device and the load in the event of an overloadcondition. The TPS54332DDA is available in an 8-pin SOIC PowerPAD?package.
