Product Overview

The LM2670T-ADJ/NOPB is a SIMPLE SWITCHER® high-efficiency step-down Voltage Regulator for use with battery chargers. The LM2670 series of regulator is monolithic integrated circuit which provides all of the active functions for a step-down (buck) switching regulator capable of driving up to 3A loads with excellent line and load regulation characteristics. High efficiency (>90%) is obtained through the use of a low on-resistance DMOS power switch. The SIMPLE SWITCHER® concept provides for a complete design using a minimum number of external components. The switching clock frequency can be provided by an internal fixed frequency oscillator (260KHz) or from an externally provided clock in the range of 280 to 400kHz which allows the use of physically smaller sized components. A family of standard inductors for use with the LM2670 are available from several manufacturers to greatly simplify the design process.
  • Simple and easy to design with (using off-the-shelf external components)
  • Up to 94% efficiency
  • 150mΩ DMOS output switch
  • 50μA Standby current when switched OFF
  • ±2% Maximum output tolerance over full line and load conditions
  • 260kHz Fixed frequency internal oscillator
  • Green product and no Sb/Br
