1A/1A Dual Channel 1.5MHz Sync. Step Down Converter
Rev. 1.2.0
GENERAL DESCRIPTION
The XRP6668 is a dual channel synchronous current mode PWM step down (buck) converter capable of delivering up to 1 Amp of current per channel and optimized for portable battery-operated applications.
Based on a current mode 1.5MHz constant frequency PWM control scheme, the XRP6668 reduces the overall ponent count and solution footprint as well as provides a low output voltage ripple and excellent line and load regulation. It also implements a PFM mode to improve light load efficiency as well as a 100% duty cycle LDO mode. Output voltage is adjustable to as low as 0.6V with a better...
