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 component 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.
