Product Overview

The LM22670TJE-5.0/NOPB is a step-down Voltage Regulator provides all of the functions necessary to implement an efficient high voltage step-down (buck) regulator using a minimum of external components. This easy to use regulator incorporates a 42V N-channel MOSFET switch capable of providing up to 3A of load current. Excellent line and load regulation along with high efficiency (>90%) are featured. Voltage mode control offers short minimum on-time, allowing the widest ratio between input and output voltages. Internal loop compensation means that the user is free from the tedious task of calculating the loop compensation components. Fixed 5V output and adjustable output voltage options are available. The default switching frequency is set at 500kHz allowing for small external components and good transient response. In addition, the frequency can be adjusted over a range of 200kHz to 1MHz with a single external resistor.
  • Internally compensated voltage mode control
  • Stable with low ESR ceramic capacitors
  • Adjustable switching frequency and synchronization
  • Precision enable pin
  • Integrated boot-strap diode
  • Integrated soft-start
  • Fully WEBENCH® enabled
  • ±1.5% Feedback reference accuracy
  • 500kHz Default Switching Frequency
  • Green product and no Sb/Br
