The LA9472A is a 2A monolithic step down switching regulator operating in continuous mode and realized in a new BCD technology allowing the integration of isolated, vertical DMOS power transistors with mixed CMOS/bipolar transistors. The device can deliver 2A at an output voltage adjustable from 5.1V to 40V and contains diagnostic and control functions that make it particularly suitable for microprocessor based systems.
Switching Regulator with L4972A

Integrated functions include a reference voltage of 5.1V at 2%, soft start, under-voltage lockout, an oscillator with feed-forward control, pulse by pulse current current limit, thermal shutdown and a reset and power failure circuit. The latter provides a
