Adjustable Frequency Buck or Buck-Boost Pre-Regulator with 2 LDOs, Window Watchdog Timer, and NPOR

The ARG81401 is a power management IC that uses a buckor buck-boost pre-regulator to efficiently convert automotivebattery voltages into a tightly regulated intermediate voltage,complete with control, diagnostics, and protections. The outputof the pre-regulator supplies a 5 V, 300 mA LDO and a 3.3 V \n• VIN operating range from 3 to 36 V, with 40 V maximum\n• Adjustable PWM switching frequency: 250 kHz to 2.4 MHz\n• Two internal LDO regulators with foldback short-circuit protection\n• Programmable window watchdog timer with a fixed activation delay of 30 ms\n• Dual bandgaps for increased reliab;
