Overview
The TPS53820RWZR is an integrated step-down converter designed by Texas Instruments for low current SVID (Serial Voltage Identification) rails in Intel CPU power supply applications. This device is optimized for supporting Intel VR13.HC SVID POL (Point of Load) applications. It features a single chip solution that provides up to two outputs, specifically for VCCANA (5.5 A) and P1V8 (4 A), making it highly suitable for Intel server platforms. The TPS53820RWZR employs D-CAP+ mode control, which ensures fast load transient performance and internal compensation, reducing the need for external components. Additionally, it offers telemetry capabilities through an I2C system interface, reporting input voltage, output voltage, output current, and temperature, along with fault conditions.
