RT7272B Datasheet | Richtek

3A, 36V, 500kHz Synchronous Step-Down Converter 1 General Description The RT7272B is a high efficiency, current mode synchronous step-down DC-DC converter that can deliver up to 3A output current over a wide input voltage range from 4.5V to 36V. The RT7272B integrates a 150m on-resistance of high-side MOSFET and an 80m on-resistance of low-side MOSFET to achieve high conversion efficiency up to 95%. The current mode control architecture supports fast transient response and simple pensation circuit. A cycle-by-cycle current limit function provides protection against shorted output and an internal softstart eliminates input current surge during start-up. The RT7272B...
