Description
LT8336HV#PBF is a high‑voltage, buck/boost DC‑DC LED driver IC from Linear Technology (Analog Devices). It supports a wide input range suitable for off‑line and automotive/high‑voltage applications and regulates current to one or more LED strings using external sense resistors. The device integrates high‑voltage MOSFETs and can operate in buck, boost, or buck‑boost modes to maintain a constant LED current over a broad input range. It provides flexible dimming (PWM and/or analog), and includes protections such as overcurrent, overvoltage, thermal shutoff, and UVLO. The #PBF suffix indicates Pb‑free, RoHS‑compliant packaging. Typical uses include automotive LED lighting, high‑voltage LED backlighting, and other constant‑current LED driver applications. For exact electrical specs, package details, and dimming/programmability options, refer to the LT8336HV datasheet.
