LM51501-Q1 Wide VIN Automotive Boost Controller

The LM51501-Q1 device is a wide input range automatic boost controller. The device can be used to maintain a stable output voltage during automotive cranking from a vehicle battery or from a back-up battery. The LM51501-Q1 switching frequency is programmed by a resistor from 220 kHz to 2.3 MHz. Fast switching (≥ 2.2-MHz) minimizes AM band interference and al.
