TPS54232DR Part Information

Details for TPS54232DR by Texas Instruments

Electronic & Electrical Components>Semiconductors - ICs>Power Management

Part Description

The TPS54232 is a 28-V, nonsynchronous 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 batterypowered 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 startup and transient conditions. A cycle-bycycle current limit scheme, frequency fold back, and thermal shutdown protect the device and the load in the event of an overload condition. The TPS54232 is available in an 8-pin SOIC package.
