MCP34845 6 channel LED driver electronic circuit project

A very simple 6 channel low cost led driver electronic circuit project can be designed using the MCP34845 LED drivers manufactured by Freescale Semiconductor .
The MCP34845 LED drivers operates from 5 to 21 volts and is specially designed for use in backlighting LCD displays from 10" to 17"+ for devices like : PC Notebooks , Netbooks , Picture Frames , Portable DVD Players , Small Screen Televisions , Industrial Displays , Medical Displays , etc. .
The MCP34845 LED drivers is capable of driving up to 16 LEDs in series in 6 separate strings.

PWM dimming is performed by applying a PWM input signal to the PWM pin which modulates the LED channels directly.
Main features of this driver circuit project are : input voltage of 5.0 to 21 V , boost output voltage up to 60 V, 2.0 A integrated boost FET , fixed boost frequency - 600 kHz or 1.2 MHz , OTP, OCP, UVLO fault detection , LED short/open protection , programmable LED current between 3.0 mA and 30 mA .
