TEXAS INSTRUMENTS  LM22678TJE-5.0/NOPB  Buck (Step Down) Switching Regulator, Fixed, 4.5V-42V In, 5V And 5A Out, 500 kHz, TO-263-7

Product Overview

The LM22678TJE-5.0/NOPB is a step-down Voltage Regulator with precision enable. It 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 that can provide up to 5A 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. 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).

  • Stable with low ESR ceramic capacitors
  • Integrated boot-strap diode
  • Integrated soft-start
  • Fully Webench® enabled
  • ±1.5% Feedback reference accuracy
  • Green product and no Sb/Br
