As can be seen in the complete schematic diagram presented below, the pulse width modulated drive signal is generated by a single gate of the far-famed CD40106BE Hex Schmitt Trigger chip (IC2), ...

High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...

Therefore, each LED driver will be a 350 mA current source designed to work from an input of 45V to 51V over a range of output voltage from 30V to 40V, reflecting the potential variation of the VF of ...

Many equipment manufacturers prefer protection circuits combining resettable overcurrent protection devices with upstream fail-safe protection. In this example, R1 represents a ballast resistor used ...

This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with many integrated analog features. The LED driver ...

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...

The driver has overtemperature and short-circuit protection, important safeguards for lighting applications. The MAX16806/MAX16805 are rated for operation over the automotive temperature range ...
