Product Overview
LT®3476 is a quad-output DC/DC converter designed to operate as a constant-current source for driving high-current LED. A fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages. A frequency adjust pin allows the user to program switching frequency between 200KHz and 2MHz to optimize efficiency and external component size. This senses output current at the high side of the LED. High-side current sensing is the most flexible scheme for driving LEDs, allowing buck, boost, or buck-boost configurations. Each current monitor threshold is trimmed to within 2.5% at the full scale of 105mV. With an external sense resistor, the user programs the output current range of each channel. Each of the four regulators is independently operated by that channel’s PWM signal. Application includes RGGB lighting, automotive and avionic lighting, TFT LCD backlighting, constant-current sources.
- LED current regulation with high-side sense
- VIN operating range from 2.8 to 16V (TA = 25°C)
- Typical nominal RT pin voltage is 1.26V (TA = 25°C)
- Typical switching frequency is 2000KHz (RT = 8.25k, TA= 25°C)
- Maximum duty cycle is 76% (RT = 8.25k (2MHz), TA = 25°C)
- Typical REF output voltage is 1.050V (10µA ≥ IREF ≥ –200µA, TA = 25°C)
- Open LED protection, low shutdown current
10µA - 38-lead plastic QFN package
- Temperature rating range from -40°C to 85°C
