Linear to release 45V, 1.3A/2.3A LED drivers for high current LED applications
SEOUL, Korea (AVING) — Linear Technology announces the ‘LT3517’ and ‘LT3518’, which are both 45V, high side current sense DC/DC converters designed to drive high current LEDs.
Their 3V to 30V input voltage range makes them ideal for a wide variety of applications including automotive, industrial and architectural lighting. The LT3517 and LT3518 are identical except for switch current limits. The LT3517 has an internal 1.3A switch, whereas the LT3518 has an internal 2.3A switch.
The LT3518 can drive up to ten 350mA white LEDs from a 12V input, whereas the LT3517 can drive five, making them ideal for a variety of applications such as automotive display backlighting. Both parts can deliver efficiencies up to 90% in boost mode from a compact 4mm x 4m…
