LM34914 Overview

Key Specifications

Mount Type: Surface Mount
Pins: 10
Operating Voltage: 40 V
Min Voltage (typical range): 8 V

Description

The LM34914 Step-Down Switching Regulator features all the functions needed to implement a low cost, efficient, buck bias regulator capable of supplying at least 1.25A to the load. To reduce excessive switch current due to the possibility of a saturating inductor the valley current limit threshold changes with input and output voltages, and the on-time is reduced when current limit is detected.

Key Features

  • Input Voltage Range: 8V to 40V
  • Integrated N-Channel buck switch
  • Valley current limit varies with VIN and VOUT to reduce excessive inductor current
  • On-time is reduced when in current limit
  • Integrated start-up regulator
