说明

  • SLUU143, 30W, 1.8V DC to DC Single Output Power Supply. Synchronous buck converter using the UCC38C43 BiCMOS low-power current-mode PWM controller, the TPS2838 synchronous buck MOSFET driver with drive regulator, and the INA138 high-side measurement current shunt monitor. The input voltage for this converter is from a 3.3-Vdc rail which draws the bias voltage for the devices from an available 12-Vdc bus. The converter is designed to operate at a switching frequency of 400kHz and supports a non-isolated 1.8-Vdc, 17-A output

Improved Energy Storage Systems with SiC Solutions from onsemi

ESS (Energy Storage System) is a crucial part on the path to net zero because it enables human store and control the renewable energy like solar and wind which is dynamic and unstable. A well-established energy storage system can store/ contribute energy for later use which reduces electricity cost/pressure during the valley/peak of electric consumption.
