Product Overview

The LM22674MRE-ADJ/NOPB is a SIMPLE SWITCHER® 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 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. 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. In shutdown mode the regulator draws only 25µA (typical). Built-in soft-start (500µs, typical) saves external components.
  • Internally compensated voltage mode control
  • Stable with low ESR ceramic capacitors
  • Precision enable pin
  • Integrated boot-strap diode
  • Integrated soft-start
  • 200mR N-channel MOSFET
  • ±1.5% Feedback reference accuracy
  • Green product and no Sb/Br
