LED Bulbs and Downlight Solutions
MR16 LED Bulb Designs
TI recognizes the challenges of designing MR16 LED lamp power solutions:
- Compatibility concerns with ELVT and ELV dimmers for retrofit applications
- Minimum load requirement for ELVT
- Smooth, flicker-free operation
- Small form factor
- Thermal concerns
Our MR16 LED reference circuits:
- Efficiently meet the minimum load requirement of the ELVT, thus avoiding start/stop cycles within the transformer. This avoids visible flicker in the lamp.
- Avoid large current spikes into the SSL lamp and ELVT
