GENERAL DESCRIPTION

The SP6669 is a synchronous current mode PWM step down (buck) converter capable of delivering up to 800mA of current and optimized for portable battery-operated applications.

Based on a current-mode 1.5MHz constant frequency PWM control scheme, the SP6669 reduces the overall component count and solution footprint. It provides low output voltage ripple and excellent line and load regulation. It also implements a 100 duty cycle LDO mode. Output voltage is adjustable to as low as 0.6V with a better than 3 accuracy while a low quiescent current 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 SP6669 is offered in a RoHS compliant, “green”/halogen free 5-pin SOT23 package.
