LT8570EDD#PBF

LT8570 is a PWM DC/DC converter. The LT8570 contains a 0.5A, 65V power switch. The LT8570 can be configured as either a boost, SEPIC or inverting converter. The LT8570 has an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, the LT8570 can be synchronized to an external clock. The switching frequency of the part may be free running or synchronized, and can be set between 200kHz and 1.5MHz. The LT8570also feature innovative active low SHDN pin circuitry that allows for slowly varying input signals and an adjustable under voltage lockout function. Additional features such as frequency foldback and soft start are integrated. Typical applications include FD bias supplies, TFT-LCD bias supplies, GPS receivers, DSL modems, local power supply.
