Voltage Regulators - DC DC Switching Regulators datasheet and documents for LP87562RRNFRQ1
Voltage Regulators - DC DC Switching Regulators Overview
The LP87562RRNFRQ1 is an automotive-grade multiphase buck converter with integrated switches, featuring a 12A + 4A configuration. It operates within a -40°C to 125°C temperature range and utilizes a 26-pin VQFN-HR (RNF) package. The device supports a maximum switching frequency of 2200kHz and provides two positive adjustable outputs ranging from 0.6V to 3.36V. With a total output current capacity of 16A, it includes synchronous rectification and controls output slew rate during start-up to minimize overshoot and in-rush current.
