# Title: MCP1664 Click Board™ ## Description: The MCP1664 Click Board™ contains 4 high-power white LEDs. It carries the MCP1664, a high-voltage step-up LED driver from Microchip. MCP1664 click is designed to run on either 3.3V or 5V power supply. It communicates with the target board microcontroller over the PWM pin on the mikroBUS™ line. Note: Don't look directly at the LEDs while they are on, you could damage your eyesight. How Does The MCP1664 Click Board Work? The click has a power input and a PWM input, so you can set the light intensity at the level you want. MCP1664 IC FEATURES The MCP1664 is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive multiple strings of LEDs with constant current powered from two and three-cell alkaline or NiMH/NiCd as well as from one-cell Li-Ion or Li-Polymer batteries. The MCP1664 features an open load protection (OLP) which turns off the operation in situations when the LED string is accidentally disconnected or the feedback pin is short-circuited to GND. While in Shutdown mode (EN = GND), the device stops switching and consumes 40 nA typical of input current.

How Does The MCP1664 Click Board Work? 

The click has a power input and a PWM input, so you can set the light intensity at the level you want.

MCP1664 IC FEATURES

The MCP1664 is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive multiple strings of LEDs with constant current powered from two and three-cell alkaline or NiMH/NiCd as well as from one-cell Li-Ion or Li-Polymer batteries.

CODE SNIPPET

This code snippet shows basic control of light brightness with PWM. The duty cycle is controlled with the potentiometer P1.

01 uint16_t current_duty;
02 uint16_t adc_rd;
03 void MCU_Init()
04 {
05 TRISC = 0; // designate PORTC pins as output
06 LATC = 0; // set PORTC to 0
07 PWM2_Init( 5000 ); // Initialize PWM2 module at 5KHz
08 }
09 void main()
10 {
11 MCU_Init();
12 current_duty = 0;
13 PWM2_Start();
14 PWM2_Set_Duty(current_duty);
15 while ( 1 ) // Playing with Potentiometer P1 you can control current PWM duty cycle
16 {
17 adc_rd = ADC_Read(1) & 0x0000FFFF; // Read 10 - bit ADC value and set newly acquired 8 - bit PWM duty
18 current_duty = adc_rd / 4 ;
19 PWM2_Set_Duty(current_duty ); // Set newly acquired duty
