LM3424 white LEDs controller circuit

This white LEDs controller circuit is designed using LM3424 high voltage N-channel MosFET controller for LED drivers.
LM3424 includes a thermal foldback for temperature management of the LEDs.

LT3754 16 channel LED driver

This 16 channel LED driver circuit is designed using LT3754 LED driver with a step-up DC DC controller designed by Linear Technology and is capable of driving up to 45V of LEDs.
Each channel of the LT3754 16 channel LED driver circuit contains an accurate current sink with ±2.8% current matching.  If are used high current Leds channels can be paralleled .

DC led driver circuit using LT3519

This DC led driver circuit project is based on the LT3519 driver manufactured by Linear Technology fixed frequency step-up DC DC converter designed to drive LEDs. The LT3519 has an integrated Schottky diode and a 750mA low side switch .
The LT3519 DC led driver circuit project has a internal fixed frequency around 400kHz and offer a wide range input voltage from 3V to 30V .
LT3519 LED driver can operate as a constant-voltage source or constant-current source. The LED current is externally programmable with a 250mV sense resistor.
