Copy A6271KLPTR-1 LED Driver IC 1 Output DC DC Controller SEPIC, Step-Down (Buck), Step-Up (Boost) Analog, PWM Dimming – 16-eTSSOP-EP [CLONE] in Pakistan

The A6271-1 is a DC-DC converter controller, providing a programmable constant-current output for driving high-power LEDs in series. The controller is based on a programmable fixed-frequency, peak current-mode control architecture. The DC-DC converter can be configured in a myriad of different switching configurations including boost, buck-boost, buck (ground-referenced switch), and SEPIC.
