The TPS54332 is a 28-V, 3.5-A non-synchronous buck converter that integrates a low-RDS(on) high-side MOSFET. To increase efficiency at light loads, a pulse-skipping Eco-Mode feature is automatically activated. Furthermore, the 1-µA shutdown supply current allows the device to be used in battery-powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis of the input undervoltage lockout. An overvoltage transient protection circuit limits voltage 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 overload condition. The TPS54332 is available in an 8-pin SOIC PowerPAD™ package.
