Part: AP1521
Category:
Power Management
-> DC-DC Converters
Description: The AP1521 is a step-up DC/DC converter<<<>>>specifically designed to drive white LEDs with a<<<>>>constant current. The device can drive two, three or<<<>>>four LEDs in series from a Li-Ion cell. Series<<<>>>connection of the LEDs provides identical LED<<<>>>currents resulting in uniform brightness and<<<>>>eliminates the need for ballast resistors. The<<<>>>AP1521 switches at 1MHz that allows the use of<<<>>>tiny external components. A low 300mV feedback<<<>>>voltage minimizes power loss in the current setting<<<>>>resistor for better efficiency
