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;
