Integrated Power Controller For LED Lighting
May 20, 2022
The STNRG012 contains a multimode power factor correction (PFC) controller, resonant half-bridge controller and 800V start-up circuit managed by a digital engine.
The PFC controller dynamically changes between transition mode, discontinuous current mode (DCM), and valley jumping for optimum efficiency.
Additional dedicated hardware IP blocks, including a power manager and burst mode engine, ensure stable operation in idle mode and minimize power consumption.
The device stores operating parameters and calibration coefficients in on-chip non-volatile memory (NVM), allowing users to customize settings and program the device during production.
Digital programming also saves external components traditionally used for configuration, reducing bill of materials and circuit size.
A UART port for monitoring and communication simplifies testing and enables real-time monitoring for increased reliability.
