The LX1671 is a highly integrated power supply controller IC featuring three PWM switching regulator stages with an additional onboard linear regulator driver. Two of the constant frequency voltage-mode PWM phases can be easily configured for a single Bi-Phase high current output or two independently regulated outputs. Each phase incorporates a fully programmabl soft-start sequence. This versatility yields either three or four independently regulated outputs with full power sequencing capability giving system designers the ultimate flexibility in power supply design.
