MaxLinear XRP6668

Beschreibung

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 operations.

Based on a current mode 1.5MHz constant frequency PWM control scheme, the devices reduce the overall component count and solution footprint as well as provide a low output voltage ripple and excellent line and load regulation. Both devices also implement 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 better than 3% accuracy while a low quiescent current supports the most stringent battery operation conditions. Built-in over temperature and under voltage lock-out protections insure safe operations under abnormal operating conditions.

XRP6668 is available in a RoHS compliant, “green” halogen free 8-pin SOIC package.
