PF5020
Overview
The PF5020 integrates multiple high performance buck regulators. It can operate as a stand-alone point-of-load regulator IC, or as a panion chip to a larger PMIC.
Built-in one-time programmable (OTP) memory stores key startup configurations, drastically reducing external ponents 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.
