Datasheet Summary
2A 18V Synchronous PFM/PWM Step-Down Regulator
February 2013
GENERAL DESCRIPTION
The XRP7674 is a 2A capable synchronous current-mode PWM step down (buck) voltage regulator with improved light current load efficiency. A wide 4.5V to 18V input voltage range allows for single supply operations from industry standard 5V and 12V power rails.
With a 340kHz constant operating frequency and integrated high and low-side 100mΩ/100mΩ MOSFETs, the XRP7674 reduces the overall ponent count and solution footprint. Current-mode control provides fast transient response and cycle-bycycle OCP. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current...
