LX1672 Overview
C OM The LX1672 is a highly integrated power supply controller IC featuring ..net two PWM switching regulator stages with an additional onboard linear regulator driver. The two constant frequency voltagemode PWM phases can be easily configured as a single Bi-Phase high current output, two independently regulated outputs, or as a DDR memory I/O supply with a tracking DDR termination voltage supply. Power loss and...
