Texas Instruments’ 2.2-MHz, dual-channel synchronous buck converter offers a unique set of features designed to significantly reduce electromagnetic interference and high-frequency noise in high-voltage dc/dc step-down applications such as automotive infotainment and high-end cluster power-supply systems. The LM5140-Q1 controller includes dual outputs with phase interleaving and is offered in wettable flank packaging that speeds manufacturing. The device’s wide 3.8-v to 65-v operating range handles start-stop and load-dump conditions for 12-V/24-V lead-acid and emerging 48-V Lithium-ion automotive batteries. According to the company, low 35-uA quiescent current (I(Q)) in standby (one channel operating with no load) extends battery life in “always on” applications. For more information, visit www.ti.com.
