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.

The Arduino is an open-source electronics prototyping platform composed of two major parts: the Arduino board (hardware) and the Arduino IDE (software). The Arduino IDE is used to write the program ..

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 ...
