Especificações Técnicas

PT4115 IS A INDUCTOR BUCK CONVERTER OF CONTINUOUS CONDUCTION MODE, USED TO DRIVE ONE OR MULTIPLE SERIES CONNECTED LED DESIGN, ONE VOLTAGE IS MORE EFFICIENT THAN WHOLE LED VOLTAGE CHAIN. THE DEVICE IS BETWEEN THE 6V AND 30V TO INPUT POWER, AND PROVIDED WITH AN EXTERNAL ADJUSTABLE OUTPUT CURRENT UP TO 1.2A.IN THE POWER SUPPLY VOLTAGE AND THE EXTERNAL COMPONENTS OF THE DIFFERENT, PT4115 OFFERS MORE THAN 30 WATTS OF OUTPUT POWER. THE PT4115 INCLUDES POWER SWITCH AND A HIGH OUTPUT CURRENT DETECTION CIRCUIT, AND USED FOR AN EXTERNAL RESISTOR TO SET THE NOMINAL AVERAGE OUTPUT CURRENT, AND A DEDICATED DIM INPUT, NO MATTER WHAT DC VOLTAGE OR PULSE LIGHT MODULATION RANGE. APPLYING A SERIES OF VOLTAGE OF 0.3V OR LOWER DIM TURNS OFF THE OUTPUT PINS, AND SWITCH A LOW CURRENT STANDBY EQUIPMENT. THE PT4115 IS AVAILABLE IN SOT89 5 PACKAGE READ AT PRESENT, PT4115 PRACTICAL LIGHTING MODULE CAN PROVIDE THREE DRIVER MODULES OF 1 PIECE OF 1W (GREEN), 3 PIECE OF 1W (BLUE) AND 1 PIECE OF 3W (RED). THE SAMPLE MODULE CAN DO SWITCH TEST WITH HALOGEN BULB FOR 100000 TIMES, IN THE SAME BRIGHTNESS OF HALOGEN LAMP, POWER CONSUMPTION CAN BE REDUCED BY HALF.
