TEXAS INSTRUMENTS  LM22674MRE-5.0/NOPB  Buck (Step Down) Switching Regulator, Fixed, 4.5V-42V In, 5V And 0.5A Out, 500 kHz, SOIC-8

Product Overview

The LM22674MRE-5.0/NOPB is a SIMPLE SWITCHER® Step-down Voltage Regulator with precision enable. This 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 500mA 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. This regulator is available in fixed output voltage of 5V version. A switching frequency of 500kHz allows for small external components and good transient response. A precision enable input allows simplification of regulator control and system power sequencing.
  • Internally compensated voltage mode control
  • Stable with low ESR ceramic capacitors
  • 200mΩ N-channel MOSFET
  • ±1.5% Feedback reference accuracy
  • Precision enable pin
  • Integrated boot-strap diode
  • Integrated soft-start
  • Fully WEBENCH® enabled
  • Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
