AL8812FDF-13

AL8812 BOOST/BUCK DC-DC CONVERTER FOR DIMMABLE MR16 LED LAMPS Description Pin Assignments The AL8812 is a monolithic control circuit containing the primary functions required for DC-to-DC converters with MOSFET in one package. These devices consist of an internal NC 1 12 DRAIN GATE 2 11 SOURCE INPUT 3 10 TIMING VCC 4 9 GND SENSE 5 8 SW/E DRIVE 6 7 SW/C temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. Additionally a 60V, 3.6A MOSFET is integrated for reduced BOM cost and size. This series is specifically designed for buck and boost applications with a minimum number of external components.
