Overview
® RT7272A 3A, 36V, 500kHz Synchronous Step-Down Converter General Description The RT7272A 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 device integrates a 150mΩ high side and a 80mΩ low side MOSFET to achieve high conversion efficiency up to 95%.
The current mode control architecture supports fast transient response and simple compensation circuit.
A cycle-by-cycle current limit function provides protection against shorted output and an internal soft-start eliminates input current surge during start-up.
The RT7272A provides complete protection functions such as input u...
