The TPS53632G device supports the standard I2C Rev 3.0 interface for dynamic control of the output voltage and current monitor telemetry. Paired with TI Ga N power stages and drivers, the TPS53632G can switch up to 1 MHz to minimize magnetic ponent size and reduce overall board space. The LMG5200 Ga N power stage is designed specifically for this controller to achieve high frequency and efficiency as high as 92% with 48-V to 1-V...
