The TPS92315 is an off-line flyback power supply controller designed for isolated LED lighting applications. It utilizes Primary-Side Regulation (PSR) to eliminate the need for an opto-coupler, processing information from the primary power switch and auxiliary winding for precise current control. The device operates in Discontinuous Conduction Mode (DCM) with quasi-resonant valley switching to reduce switching losses and maximize efficiency. It features a maximum switching frequency of 130 kHz and a patent-pending frequency jitter scheme to simplify EMI compliance.
