Description

The LT8570 and LT8570-1 are PWM DC/DC converters. The LT8570 contains a 0.5A, 65V power switch, while the LT8570-1 contains a 0.25A, 65V power switch. The LT8570 and LT8570-1 can be configured as either a boost, SEPIC or inverting converter.The LT8570/LT8570-1 have an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, the LT8570/LT8570-1 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 LT8570/LT8570-1 also feature innovative SHDN pin circuitry that allows for slowly varying input signals and an adjustable undervoltage lockout function.Additional features such as frequency foldback and softstart are integrated. The LT8570/LT8570-1 are available in tiny thermally enhanced 3mm ? 3mm 8-lead DFN and 8-lead MSOP packages.Applications VFD Bias Supplies TFT-LCD Bias Supplies GPS Receivers DSL Modems Local Power Supply
