3 Description
The TPS55330 is a monolithic nonsynchronous switching
regulator with integrated 5-A, 24-V power switch. The device can be configured in several standard switching-
regulator topologies, including boost, SEPIC, and isolated flyback. The device has a wide input voltage range to support applications with input voltage from multicell batteries or regulated 3.3V, 5-V, and 12-V power rails.
The TPS55330 regulates the output voltage with current mode PWM...
