TPS56520 - Synchronous Step-Down Voltage Regulator

Download the TPS56520 datasheet PDF. This datasheet also covers the TPS56C20 variant, as both devices belong to the same synchronous step-down voltage regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPS56X20 is a synchronous DC-DC converter IC (integrated circuit) with a voltage scaling control to power up micro-processors (MCUs) requiring core voltage (VCORE) tune-ups.

After the initial power-up, the output voltage can be programmed/scaled by VID codes sent over an I2C compatible bus.

Key Features

  • I2C Compatible Interface.
  • Output Voltage (VID): 0.6V to 1.87V in 10mV.
  • Auto-Skip Eco-mode™ ON/OFF (Light-load).
  • Current Limit Target: 40% to 160%.
  • Enabling IC, Reading-back Power-good.
  • Hiccup Mode Protection ON/OFF.
  • IC Terminal Features.
  • Start-up by Using External Resistors Output Voltage with VFB Pin: 0.6V to 1.87V.
  • Adjustable Soft-start, Monotonic Pre-Biased Start-up.
  • Power-good.
  • I2C Address Programming.
