Datasheet - L7983PU50R

The soft-start time is internally fixed and the output voltage supervisor manages the reset phase for any digital load (microcontroller, FPGA, etc.).

The internal compensation network features high noise immunity, simple design and saves on the component cost.

The RST open collector output can also implement output voltage sequencing during the power-up phase.

The synchronous rectification, designed for high efficiency at medium - heavy load, and the high switching frequency capability make the size of the application compact.

Pulse-by-pulse current sensing on both power elements implements an effective constant current protection.
