LM5150-Q1 Low IQ Boost Controller

Texas Instruments LM5150-Q1 Low IQ Boost Controller is a wide input range automatic boost controller. The device is suitable for use as a pre-boost converter which maintains the output voltage from a vehicle battery during automotive cranking or a backup battery during the loss of a vehicle battery. A resistor programs the LM5150-Q1 switching frequency from 220kHz to 2.3MHz. Fast switching (≥ 2.2MHz) minimizes AM band interference and allows for a small solution size and fast transient response.
