LTM8022 DC to DC Converter and Switching Regulator Chip 3.201VDC to 3.399VDC Output Demonstration Circuit

The is an demonstration board features LTM8022 step down µModule regulator delivering a 3.3V output from a 4.5V to 36V input supply. The LTM8022 is a complete 1A, DC to DC step down power supply. Included in the IC package are the switching controller, power switches, inductor and all support components. The low profile package 2.82mm enables utilization of unused space on the bottom of PC boards for high density point of load regulation. As a step down converter, the LTM8022 requires a minimum amount of headroom to keep the output in regulation. The device may be synchronized to an external clock or allowed to enter low ripple burst mode operation at light load conditions by applying the appropriate signal to the SYNC pin. Current sharing with another LTM8022 is enabled by tying the VIN, VOUT and SHARE pins together to support higher output loads.
