Analog Devices Inc. LTC7852 Demo Circuits DC2631A
Analog Devices Inc. LTC7852 Demo Circuits DC2631A feature two LTC7852 High-Efficiency and High Output Current Step-Down Converters, each with a corresponding assembly type. These demonstration circuits offer differential sensing for the output voltages VOUT1 and VOUT2. The DC2631A Demo Circuits also offer IMON pins to monitor the inductor current of each rail. The LTC7852 converter for the -A assembly provides two 3-phase outputs of 1V, 100A and 1.5V, 100A while the -B assembly provides a single 6-phase 1V, 200A output. Both converters operate from a 7V to 14V input voltage range at a switching frequency of 400kHz.
