30 W Automotive 2 MHz Preregulator, Non-Isolated, Synchronous Buck Reference Design Based on NCV891930

30 W Automotive 2 MHz Pre-Regulator, Non-Isolated, Synchronous Buck, NCV891930-Based Reference Design

Overview

This reference design describes the operation and performance of the NCV891930 automotive synchronous buck controller with a NVMFD5C478NL 40 V dual N−channel FET. The design demonstrates the NCV891930 controller capabilities as well as a complete designed for an automotive pre-regulator for broad range of applications.

It is intended for the power supply designer to adopt the circuit directly into a typical system design, making only minimal component changes based on system requirements.

The design is meant to be a complete solution, but it also provides access to key features of the NCV891930. These include integrated compensation, low IQ and continuous synchronous mode, wide input range, overcurrent protection, external synchronization, adaptive non-overlap drivers, integrated spread-spectrum and undervoltage lockout.
