The paper proposes a triple-output buck topology as a practical, line-fed, high-power-LED lamp driver. The presented application consists of a 20 W, 500 kHz switching converter, designed to drive a 1000 lm white-light, solid-state lamp. Key features of the proposed topology are the capability to achieve high step down ratios, a reduced voltage stress on the active components and the capability to automatically balance the average current on its three outputs.

Abstract

The paper proposes a triple-output buck topology as a practical, line-fed, high-power-LED lamp driver. The presented application consists of a 20 W, 500 kHz switching converter, designed to drive a 1000 lm white-light, solid-state lamp. Key features of the proposed topology are the capability to achieve high step down ratios, a reduced voltage stress on the active components and the capability to automatically balance the average current on its three outputs.
