PL8333中文资料36V, 3.1A Monolithic Step-Down Switching Regulator数据手册Powlicon规格书

描述 Description

PL8333 is a monolithic 36V, 3.1A step-down switching converter. PL8333 integrates a 36V 79mΩ high side and a 36V, 62mΩ low side MOSFETs to provide 3.1A continuous load current over a 6.5V to 36V wide operating input voltage with 33V input over voltage protection. Peak current mode control provides fast transient responses and cycle-by-cycle current limiting. Programmable soft-start prevents inrush current at power-up.
