TPS92561EVM-001: 45mA @ 250V Max, 10.75W, 120Vin

The TPS92561EVM is a 12-W maximum, 120-VAC non-isolated dimmable LED driver whose form factor is intended for A-15, A-19, A-21, A-23, R-20, R-25, R-27, R-30, R-40, PS-25, PS-30, PS-35, BR-30, BR-38, BR-40, PAR-20, PAR-30, PAR-30L, G-25, G-30, G-40, and other LED bulbs.

The TPS92561EVM implements a dimming solution using the TPS92561 integrated circuit from Texas Instruments. The TPS92561 is a boost controller for LED lighting applications utilizing high-voltage, low current LEDs.

The boost converter topology allows the creation of the smallest volume converter possible as well as enabling high efficiencies beyond 90%. The device incorporates a current sense comparator with a fixed offset enabling a simple hysteretic control scheme free of the loop compensation issues typically associated with a boost converter. Integrated overvoltage protection (OVP) and a VCC regulator further simplify the design procedure and reduce external component count.
