Beschreibung
- 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
