L6732 is an adjustable step-down controller produced by ST company. It has synchronous rectification, input voltage range 1.8V-14V, output voltage range 0.6V-14V, programmable high and low side RDS(on) sense over-current protection, soft-start and inhibit, pre-bias start-up capability, master/slave synchronization with 180° phase shift, overvoltage protection, thermal shutdown and other features.
The L6732 is an integrated circuit designed for high performance step-down DC-DC and niPoL converters. It utilizes BCD5 fabrication to drive N-channel MOSFETs in a synchronous rectified buck topology, regulating output voltage down to 0.6V with high accuracy. The device includes features such as selectable switching frequencies, master/slave synchronization, and comprehensive protection mechanisms including thermal shutdown and over-current protection.
