1 Introduction

The TPS6521401 PMIC is a cost and space optimized solution that has flexible mapping to support the power requirements from different processors and SoCs. The PMIC includes 3 Buck regulators and 2 Low Drop-out Regulators (LDOs) with I2C, GPIOs, and configurable multi-function pins. The device also contains One-Time Programmable (OTP) Non-Volatile Memory (NVM) that is loaded to the device registers when entering the INITIALIZE state. This document describes the default configuration programmed on the TPS6521401.

Note: The NVM configuration described in this document is ideal for the application described below but can also be used to power other processors or SoCs with equivalent power requirements.

  • Processor: AM62L
  • CORE voltage: 0.75V
  • Memory: LPDDR4
  • Input Supply (VSYS, PVIN_Bx): 3.3V
  • A hardware solution is readily available with the AM62L EVM using TPS6521401 (TMDS62LEVM)
