TPS54232

illustrate

该TPS54232是一个28伏，非同步降压转换器，它集成了一个低R_{DS (Day)}High-side MOSFETs. To increase efficiency at light loads, the pulse-skipping eco-mode ™ function is activated automatically. In addition, a 1μA shutdown supply current makes the device a battery-powered application. Internal slope compensation current-mode control simplifies external compensation calculations, reducing component count while allowing the use of ceramic output capacitors. The input undervoltage lockout of a resistor divider scheme is hysteresis. Transient overvoltage protection circuitry limits start-up and transient overshoot voltage conditions. When the load is overloaded in the planned cycle current limit, frequency foldback and thermal shutdown protection device and cycle.
