With a form factor of only x x it is ideal for many applications where size and e ciency is essential. Various output currents are available: 350mA, 500mA,700mA, and 1000mA. Applying a square wave to the dimpin with voltages ranging from 1V 30V can dim the Minipuck down to 5%.

For example, a 350mA Minpuck will drive up to six series LEDs, with a 3V forward voltage per LED totaling 18V, with a VIN of 24 VDC. Due to the nature of a buck regulator, the input voltage must always be higher than the forward voltage of the LEDs. Figures 2-4 show various drive current Minipucks driving multiple LED con gurations. Note the parallel strings of LEDs can be driven directly with no additional circuitry required to ensure current sharing. The nature of LEDs themselves will provide su cient current sharing if the parallel strings are comprisedof three or more series LED strings.

5 Dim PinThe Minipuck can be turned on and o by applying voltage to the PWM Control Pin with a voltage range of1-30 VDC. Figure 4 depicts a microcontroller such as an Arduino used to dim the Minipuck . In this case a logic high signal will cause the output of the Minipuck to be o , and a logic low signal will cause the output to be on . A square wave frequency of 100Hz -2 KHz should be used with a minimum of 100ns on-time and 100ns o -time. Note frequencies above 2 KHz should not be used as the internal capacitance of the circuitry may give unexpected results. Figure 1.
