The LT3755IUD-1#PBF is a member of the Led monitor current sinking family of Power Management ICs (PMICs) and is the only device of its kind to offer a monolithic package with integrated timer, switch and current sink. This driver is capable of providing constant current drive to a wide variety of LED loads in a range of applications, including automotive, automotive displays, industrial, medical, and home automation.

The LT3755IUD-1#PBF driver is designed to operate from a single 2.7 to 6 V supply or can be stepped up using a simple external flyback transformer. The device is capable of maintaining constant current over temperature and with varying input voltage, thus providing maximum efficiency, accuracy and long life to LEDs. The driver also features fast warmup times and programmable pulse width modulation (PWM) control for dimming and other brightness control applications.

The LT3755IUD-1#PBF driver uses a proprietary current regulation method which allows it to achieve fast warmup times and high current accuracy. The device includes an internal loop compensation network and a high-current, adjustable sink. With bidirectional operation and temperature compensation, the LT3755IUD-1#PBF can provide up to 3A drive current per channel. The device can also provide a wide range of dimming states, from full-on to completely off, with very high on/off contrast.

The LT3755IUD-1#PBF driver also features an onboard timer which can be used for either soft start or LED flashing. The timer can be used for both regular and pulse-width-modulation (PWM) control of LED brightness, with an adjustable frequency and duty cycle. The driver also offers a built-in over-temperature fault monitor, making it suitable for environments with extreme temperature swings. The device is designed to operate over a temperature range of -40°C to 125°C.

The LT3755IUD-1#PBF driver is suitable for automotive lighting, automotive displays, industrial lighting, medical applications and home automation. It is well suited for LED-based displays, LED strip lighting, LED sign boards, LED panel lights, LED bulbs, LED ceiling lights as well as LED street lighting. With its small form factor and high current capacity, the LT3755IUD-1#PBF is an ideal solution for applications where space is at a premium.
