TPS54232DR

TEXAS INSTRUMENTS  TPS54232DR  直流-直流开关降压, 逐步递降稳压器, 可调, 3.5V-28V输入, 800mV-25V/2A输出, 1MHz, SOIC-8 新

The TPS54232 is a 28-V, nonsynchronous buck converter that integrates a low RDSon 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 startup and transient conditions. A cycle-by-cycle 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.
