LT8570EDD#PBF

LINEAR TECHNOLOGY  LT8570EDD#PBF  直流-直流开关升压, 反相, SEPIC稳压器, 可调, 2.55V-40V输入, 500mA输出, 1.5MHz, DFN-8

The is a PWM DC-to-DC Converter with 0.5A/65V power switch, integrated soft-start function and synchronization. It can be configured as either a boost, SEPIC or inverting converter. It has an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, it 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. It also features innovative SHDN pin circuitry that allows for slowly varying input signals and an adjustable undervoltage lockout function. Additional features such as frequency foldback and soft-start are integrated.
