1 Overview

The PF5023 integrates multiple high performance buck regulators. It can operate as a stand-alone point-of-load

regulator IC, or as a companion chip to a larger PMIC.

Built-in one-time programmable (OTP) memory stores key startup configurations, drastically reducing external

components typically used to set output voltage and sequence of regulators. Regulator parameters are

adjustable through high-speed I2C after start up offering flexibility for different system states.
