TPS54232DR: MOSFET, Pinout, Datasheet

The TPS54232DR is a nonsynchronous buck converter with a low RDS(on) high-side MOSFET that functions at 28 V. A pulse-skipping Eco-Mode feature is automatically enabled to optimize efficiency at light loads. The device can also be used in battery-powered applications because to the 1-A shutdown supply current. Current mode control with internal slope compensation minimizes component count and simplifies external compensation calculations while permitting the use of ceramic output. The hysteresis of the input undervoltage lockout is programmed using a resistor divider. During startup and transient conditions, an overvoltage transient protection circuit prevents voltage overshoots. In the event of an overload condition, the device and the load are protected by a cycle-by-cycle current restriction mechanism, frequency fold back, and thermal shutdown. In an 8-pin SOIC package, the TPS54232DR is available.
