Description
The XRP6668 is a dual synchronous current mode PWM step down (buck) converter capable of delivering up to 1Amp 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 cycle LDO mode. Output voltage is adjustable to as low as 0.6 with a better supports the most stringent battery operating conditions.Built-in over temperature and under voltage lock-out protections insure safe operations under abnormal operating conditions.The xrp6668 is offered in a RoHS compliant, ''green''/halogen free 8-pin exposed pad SOIC package.
