Description

The LM5177 is a four switch buck-boost controller. The device provides a regulated output voltage if the input voltage is higher, equal, or lower than the adjusted output voltage.

Key Features

  • Wide input range from 3.5V to 60V (85V absolute maximum) – Minimum 2.8V when V(BIAS) > 3.5V
  • Output voltage from 3.3V to 60V
  • Low shutdown IQ of 3μA
  • Low operating IQ of 60μA
  • 3% reverse current limit accuracy for precise charging currents
  • Average input and output current monitor or limiter
  • Dynamic output voltage tracking for PWM or analog input signals
  • Power save mode (PSM) selectable for high light load efficiency
  • Two integrated high-voltage supply LDOs with automatic selection
  • 2A peak current logic level gate driver – Integrated bootstrap diode – Bootstrap overvoltage and undervoltage protection
