Maxim Integrated MAX16840 Evaluation Kit MAX16840EVKIT# MAX16840EVKIT# データシート

The  MAX16840  evaluation  kit  (EV  kit)  demonstrates  the 
MAX16840 HBLED driver IC used for solid-state lighting 
(SSL)  applications.  The  EV  kit  is  configured  in  a  buck-
boost topology providing an output power of 5.5W for 3 
to 5 LEDs. The IC is designed for standard multifaceted-
reflector  (MR)  applications.  The  EV  kit’s  typical  input 
power  is  6.7W  at  12V  AC  and  features  a  power-factor 
correction of 0.9 (typ).
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 dimmable with some 
electronic  transformers  and  trailing-edge  dimmer  com-
bination  and  some  magnetic  transformers  and  leading-
edge dimmer combination.
