LMR22007 Switching Regulator


TI's SIMPLE SWITCHER® nano regulator 2.7-20 VIN, 750 mA synchronous step-down converter

Texas Instruments' LMR22007 is a switching regulator designed for the high-efficiency requirement of applications with stand-by and shut-down modes. The device features a low-current mode to maintain efficiency under light-load conditions, and an adaptive on-time control architecture for fast transient response.

The LMR22007 can deliver up to 750 mA of continuous load current with an adjustable input current limit. The device has a wide input voltage range of 2.7 to 20 V, and supports VIN transients to 24 V. Other features include internal compensation, internal soft start, input under-voltage protection, internal bootstrap diode, and thermal shutdown.

Features
  • High efficiency: greater than 90% at 12 VIN to 5 VOUT
  • Adjustable input current limit from 150 to 600 mA
  • Input voltage range: 2.7 to 20 V
  • Adjustable output voltage from 0.9 to 5.5 V
  • Up to 750 mA output current
 
  • Ultra-low quiescent current (18 µA typical)
  • Ultra-low shutdown current (300 nA typical)
  • < +/-2% VOUT ripple at no load
  • < +/-1% VOUT ripple at full load
  • Internal compensation, soft-start, and thermal shutdown
