PM2071-----DC LED single-segment linear driver chip
PM2071-----DC LED single segment linear driver chip
Overview
PM2071 is a powerful built-in MOSFET linear constant current LED driver chip. The power supply system has a simple structure and can achieve excellent constant current characteristics with only a few external components. While realizing the simplified peripheral circuit and smaller driver volume, the system cost is greatly reduced.
PM2071 integrates a programmable constant current driver, which supports both independent use and parallel use of multiple ICs to achieve higher power applications. PM2071 supports PWM or analog dimming function; an over-temperature compensation circuit is integrated inside to avoid thermal failure of the driver.
PM2071 also integrates various protection functions, including output short circuit, output open circuit, CS open circuit protection, thus improving the reliability of LED constant current power supply.
