LT8580EMS8E#PBF

LINEAR TECHNOLOGY  LT8580EMS8E#PBF  直流-直流开关升压, 反相, SEPIC稳压器, 可调, 2.55V-40V输入, 1A输出, 1.5MHz, MSOP-8

The is a Boost/SEPIC/Inverting DC/DC Converter with an internal 1A, 65V switch, soft-start and synchronization. The LT8580 has an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, the LT8580 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 under-voltage lockout function. Additional features such as frequency fold back and soft-start are integrated. This uses a constant-frequency, current mode control scheme to provide excellent line and load regulation. It has an FBX pin architecture that can be used for either non-inverting or inverting configurations.
