MaxLinear XRP6658 | Demoboard XR6658EVB

Description

The XRP6658 is a synchronous current mode PWM step down (buck) converter capable of delivering up to 1 Amp of current and optimized for portable battery-operated operations. Based on a current mode 1.5MHz constant frequency PWM control scheme, the XRP6658 reduces the overall component count and solution footprint as well as providing 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 as low as 0.6V with a better than 3% accuracy while a low quiescent current supports the most stringent battery operations conditions. Built-in over temperature and under voltage lock-out protections insure safe operations under abnormal operating conditions.The XRP6658 is offered in a RoHS compliant, “green”/halogen free 5-pin SOT23 package.
