DESCRIPTION TOKO TK65600B,TK65600B-G White LED Driver IC has been optimized for battery powered systems where power consumption and size are primary concerns. High efficiency has been optimized for this application. The miniature Flip Chip package device, together with the miniature Toko Coil D3313FB or Low Profile D412F Coil, further helps system designers reduce the space required to drive the white LEDs. The IC uses Current-mode PWM (Pulse Width Modulation) method of regulating the current through the string of LEDs. This time-proven method of regulation works at a fixed switching frequency which is preferred in RF systems, because the switching noise RF spectrum is more predictable. With a switching frequency of 700 kHz the operation of the IC should not disturb 455 kHz IF subsystem. The Enable pin can take a PWM signal provided by the user to reduce the display brightness. A PWM signal is preferred to pulse the LEDs with a regulated value of current and to maintain better consistency of chromaticity. 4.
