An input-adaptive self-oscillating boost converter is proposed for wide-range ultralow voltage input LED driving with tight input regulation, low cost, high efficiency, and high reliability. It consists of a self-oscillation unit, a rectification unit, and an input-adaptive peak-current control unit with a blanking time control branch and an open-circuit protection branch. In this paper, its operation...
An input-adaptive self-oscillating synchronous boost converter is proposed for ultra-low wide-range voltage input LED driving with tight input regulation, low cost, and high efficiency. It consists of a self-oscillation unit, a synchronous rectification unit, and an input-adaptive peak-current control unit including a blanking time control branch. In the paper, its operation principle including an...
