Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the ... additional driver ...

From 48V±5% a buck LED driver can be used to drive 10 LEDs in series ... a minimum off-time of 300ns to refresh the “bootstrap” capacitor (C2), part of the circuit that drives the internal power FET.

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. Dubbed DER-322, the circuit is desigend to fit neat ...

At the heart of the Arduino platform is an AVR microcontroller, in usual way you need a special hardware programmer and suitable hex files to program the Atmel AVR ... s already stored inside.
