LM22679 - Step-Down Voltage Regulator

Datasheet Summary

Description

The LM22679 switching regulator provides all of the functions necessary to implement an efficient highvoltage step-down (buck) regulator using a minimum of external components.

This easy-to-use regulator incorporates a 42-V N-channel MOSFET switch that can provide up to 5 A of load current.

Features

  • New product available: LM61460 3-V to 36-V, 6-A low EMI synchronous converter.
  • Wide input voltage range: 4.5 V to 42 V.
  • Internally compensated voltage mode control.
  • Stable with low-ESR ceramic capacitors.
  • 100-mΩ N-channel MOSFET.
  • Output voltage options: -ADJ (outputs as low as 1.285 V) -5.0 (output fixed to 5 V).
  • ±1.5% feedback reference accuracy.
  • Switching frequency of 500 kHz.
  • 40°C to 125°C operating ju.
