LED Driver Drives up to six Strings of 10 LEDs Each
Linear Technology has announced the LT3598, a 45V, 2.5MHz DC/DC boost mode converter designed to operate as a constant current LED driver for up to sixty white LEDs. The LT3598 can drive up to six strings of LEDs, each with up to ten 30mA white LEDs in series while delivering efficiencies up to 90%. Its multichannel capability makes it ideal for medium sized TFT-LCD backlighting applications. Its input voltage range of 3V to 30V makes it ideal fo...
60V Step-Down Drives 3 Strings of Ten 100mA LEDs with 10,000:1 True Color PWM DimmingHeadline
Linear Technology announces the LT3596, a 60V, 1MHz step-down DC/DC converter designed to operate as a constant current LED driver for up to 30 LEDs. From a 48V input, the LT3596 can drive up to three strings of LEDs, each with up to ten 100mA LEDs in series, delivering efficiencies of over 90%. The LT3596’s multichannel capability makes it ideal for LED billboards as well as industrial and medical displays. Its input voltage range of 6V to 60...
Triple Output LED Driver Drives Up to 24 x 500mA LEDs & Offers a 150˚C Maximum Junction Temperature
Linear Technology announces the H-grade version of the LT3496. The LT3496 is a 2MHz DC/DC converter designed to operate as a three-channel constant current LED driver. Each of the device’s three channels can drive up to eight 500mA LEDs in series, enabling it to drive up to 24 x 500mA LEDs at efficiencies up to 96%. The H-grade version operates up to a junction temperature of 150˚C, compared to the E- and I-grade versions’ 125˚C max...
