Figure 39. Efficiency Measurement for the
Demoboard (V f = 3.2 Nominal)
Figure 39 represents the efficiency of the converter
driving a single LED at a nominal current of 690 mA. The
addition of the AC bridge rectifier contributes addition
losses into the circuit and it is recommended to us low
forward voltage schottky rectifiers to minimize power
dissipation in the AC rectification stage.

MR 16 Evaluation Board Information
A specific two sided demo board was designed to fit with
the MR 16 form factor. The schematic is almost the same for
both, but the PWM dimming control circuitry has been
removed. If the same components are used, the operation
frequency will be slightly higher due to the lower pin
capacitance because the dimming transistor contribution is
removed.
