XRP7674
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 component 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 dro...
