LM51231-Q1 Boost Controller

Texas Instruments LM51231-Q1 Boost Controller provides a wide input range and employs a peak current mode control. The wide input range supports automotive cold-crank and load dump. The minimum input voltage can be as low as 0.8V when BIAS is equal to or greater than 3.8V on the device. The LM51231-Q1 features an output voltage that can be dynamically programmed using the tracking function. At the same time, the bypass mode operation is automatically entered when VSUPPLY > VLOAD, eliminating the body diode drop of the high-side MOSFET. The switching frequency is dynamically programmed with an external resistor from 100kHz to 2.2MHz. Switching at 2.2MHz minimizes AM band interference and permits a small solution size and fast transient response.
