LT3595: 16-Channel LED Driver Drives Up to 160 50mA LEDs & Offers 5000:1 True Color PWMTM Dimming
(PresseBox) (MILPITAS, CA, )The LT3595 uses 100mA, 45V internal switches. An external resistor sets the LED current for all 16 channels and dimming is then controlled for each channel using individual PWM pins. The relative current matching among the 16 drivers is 8%, ensuring uniform LED brightness. The LT3595 also enables LEDs to be disconnected in shutdown, open LED and thermal protection.
The LT3595EUHH is available from stock in a thermally enhanced 56-lead 5mm x 9mm QFN package.
