LX1671 Description
C OM The LX1671 is a highly integrated power supply controller IC featuring ..net 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 programmable soft-start sequence.
