LM27402SQ Integrated Circuit Chip High-Performance Synchronous Buck Controller With DCR Current Sensing
Product Description Of LM27402SQ
LM27402SQ is a voltage-mode, synchronous, DC/DC step-down controller with lossless inductor DCR current sensing capability. Sensing the inductor current eliminates the need to add resistive powertrain elements, which increases overall efficiency and facilitates accurate, continuous current sensing. A 0.6-V ±1% voltage reference enables high accuracy and low voltage capability at the output. An input operating voltage range of 3 V to 20 V makes the LM27402SQ suitable for a large variety of input rails.
