The LED Driver Click Board™ carries the MCP1662 high-voltage step-up voltage driver from Microchip. The LED Driver Click Board™ is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over PWM pin on the mikroBUS™ line.
The MCP1662 device is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive LED strings with a constant current from a two- or three-cell alkaline or lithium Energizer®, or NiMH/NiCd, or one-cell Lithium-Ion or Li-Polymer batteries.
The device integrates a 36V, 800 mW low-side switch, which is protected by the 1.3A cycle-by-cycle inductor peak current limit operation.
The LED Driver Click Board™ has a power input and a PWM input, so the LED lights can be dimmed. It's a great choice for driving LED strips.

The MCP1662 device is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimised to drive LED strings with a constant current from a two- or three-cell alkaline or lithium Energizer', or NiMH/NiCd, or one-cell Lithium-Ion or Li-Polymer batteries.
The device integrates a 36V, 800mW low-side switch, which is protected by the 1.3A cycle-by-cycle inductor peak current limit operation.
LED driver Click has a power input and a PWM input, so the LED lights can be dimmed. It's a great choice for driving LED strips.

Code examples for the LED Driver Click Board™, written for MikroElektronika hardware and compilers are available on Libstock.
The following code snippet shows the LED driver click example, which initializes ADC and PWM and sets the PWM output depending on the potentiometer analog input.
01 void systemInit()
02 {
03 TRISC = 0; // designate PORTC pins as output
04 LATC = 0; // set PORTC to 0
05 PWM2_Init( 5000 ); // Initialize PWM2 module at 5KHz
06 }
07
08 void main()
09 {
10 systemInit();
11 currentDuty = 0;
12 PWM2_Start();
13 PWM2_Set_Duty(currentDuty);
14
15 while ( 1 ) // Playing with Potentiometer P1 you can control current PWM duty cycle
16 {
17 currentDuty = ADC_Read(1) & 0x0000FFFF; // Read 10 - bit ADC value and set newly acquired 8 - bit PWM duty
18 currentDuty = currentDuty / 4;
19 PWM2_Set_Duty(currentDuty ); // Set newly acquired duty
