The CXLE8132 IS step-up DC/DC converters designed to drive up to six LEDs in series from a Li-Ion cell.Series connection of the LEDs provides identical LED currents and eliminates the need for ballast resistors.These devices integrate the Schottky diode required exter-nally on competing devices. Additional features include output voltage limiting when LEDs are disconnected, one-pin shutdown and dimming control. The CXLE8132 has
internal soft-start.
The CXLE8132 switches at 1.2MHz, allowing the use of tiny external components. Constant frequency switching results in low input noise and a small output capacitor.Just 0.22μF is required for 4-, 6- or 8-LED applications.
