Overview

This reference design supports the supply and acts as an indicator for a fuel injector using the TPS61161-Q1, which the boost converter drives the input from 5V-12V to 30V output. The design is set to be efficient and accurate with flexible control and a precise reference voltage.

Features
  • Wide input operating voltage from 2.7V to 18V
  • Each 10 LEDs have up to 38V open LED protection
  • Built-in soft start feature
  • Flexible digital and PWM brightness control
  • 200mV reference voltage with ±2% accuracy
  • The device has up to 90% efficiency
