The MAX16840L low-power (5W input) evaluation kit (EV kit) demonstrates the MAX16840 HBLED driver IC used for Solid State Lighting (SSL) applications. The EV kit is configured as a buck-boost topology for 3 to 5 LEDs with an output power of 4W. The device is designed for standard MR16 applications. The typical input power from 12V AC is 5W.
The EV kit is a fully assembled and tested surface-mount PCB designed and optimized to accommodate an MR16 application form factor. The EV kit is compatible with electronic and magnetic transformers.
SSL MR16 lamps face compatibility issues with electronic transformers at low power levels. If the current drawn from an electronic transformer is below a certain level it stops operating, which could cause visible flicker from the lamp. Due to compatibility issues with electronic transformers at low power levels, active power-factor correction (PFC) is not featured in this EV kit.
To improve its compatibility with electronic transformers at low power levels, an input electrolytic capacitor is included on this EV kit. For this reason, it is not dimmable.
