PL5901中文资料100V, Synchronous PWM Buck Controller数据手册Powlicon规格书

描述 Description

PL5901 is a high voltage PWM controller designed for high performance synchronous Buck DC/DC applications with input voltages up to 100V.

PL5901 drives a pair of external N − MOSFETs. The switching frequency is programmable from 50 kHz up to 500 kHz allowing the flexibility to tune for efficiency and size. The output voltage can be precisely regulated using the internally 1.2 V reference voltage for low voltage applications.

Protection features include user programmable under voltage lockout, over voltage lockout and over current protection. The supply current drops below 10µA in shutdown mode. PL5901 is a good choice for car infotainment application, telecom bus converter, etc.
