PM2071LED single segment linear driver chip
PM2071 is a powerful built-in MOSFET linear constant current LED driver chip. The power system has a simple structure and only needs to be very
Very good constant current characteristics can be achieved with few external components. In the realization of simplified peripheral circuits, smaller driver body
At the same time, the system cost is greatly reduced.
PM2071 integrates a programmable constant current driver, which supports independent use and parallel use of multiple ICs to achieve more
high 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 LED
Reliability of constant current power supply.
