Fairchild Semiconductor International (South Portland, ME) announced its FAN5607 constant-current, parallel LED driver, which provides analog and/or PWM brightness control for LCD backlighting in ultra-portable applications. The FAN5607 has a three-mode charge pump and reaches 93% peak efficiency.
Internal auto-sense circuitry maintains high efficiency, even when driving less than a maximum of four LEDs, and ensures very tight current matching over the full range of the LED’s current. In addition to providing high peak efficiency, the internal circuitry of the FAN5607 saves space and simplifies designs when compared to competitive parts that require an external control signal to maintain efficiency when driving less than four LEDs. To further reduce space in hand-held designs, the FAN5607 is offered in a small 4 mm x 4 mm molded leadless package.
The FAN5607 is priced at $0.90 for 1,000-piece quantities. Available now, delivery is in eight weeks ARO.
