Quality Control: Learn More
Analog Devices Inc. LT3955IUHE is a versatile LED driver IC featuring a True Color PWM™ series designation. This DC-DC regulator operates as a flyback, SEPIC, buck, or boost converter, supporting a wide input voltage range from 4.5V to 60V. It integrates internal switching capability and can deliver up to 3.5A (switch). Dimming is supported through both analog and PWM methods. The device operates efficiently across a temperature range of -40°C to 125°C (TJ). Its 36-QFN (5x6) package with an exposed pad is designed for surface mounting. Applications include automotive lighting, industrial illumination, and general display backlighting. The switching frequency is adjustable from 100kHz to 1MHz.
