This 6 channel LED driver circuit is designed using MCP34845 ic
manufactured by Frescale Semiconductor with integrated power supply .
The MCP34845 6 channel LED driver circuit 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.
6 Channel LED Driver Circuit Diagram:
The MCP34845 LED driver 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 electronic 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.
