Output voltage | 5V |
Load current | 600mA |
This reference design requires 5V for the gate drivers (UCC27517 device) and GaN device (the LMG2100R044), subsequently stepped down to 3.3V for the MSPM0G1506 device and other components, to operate. To generate the 5V line from the power lines (panel), a wide VIN buck, switching regulator is needed to support a maximum panel voltage of 60 V.
The TPSM365R6V5 device is a 5V fixed output, wide VIN, frequency adjustable buck regulator with integrated inductor and boot capacitor that provides cost effective, compact, and highly-efficient power conversion design. See the Application and Implementation section of the TPSM365R6, TPSM365R3 3-V to 65-V Input, 600-mA/300-mA, 4-μA No-Load IQ Synchronous Buck Converter Power Module in a HotRod™ QFN Package as a starting point for this design; however, an input below 12V was not supported during testing.
