Product Overview
LT3466 is a dual full function step-up DC/DC converter specifically designed to drive upto 20 white LEDs (10 in series per converter) with a constant current. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors and expensive factory calibration. The two independent converters are capable of driving asymmetric LED strings. The dimming of the two LED strings can also be controlled independently. It is ideal for providing backlight for main and sub-displays in cell phones and other handheld devices. This device operating frequency can be set with an external resistor over a 200KHz to 2MHz range. A low 200mV feedback voltage minimizes power loss in the current setting resistor for better efficiency. It is used in application such as main/sub displays, digital cameras, sub-notebook PCs, PDAs, handheld computers, automotive etc.
- Independent dimming and shutdown control of the two LED strings
- Internal schottky diodes
- Open LED protection (39.5V max VOUT)
- 81% efficiency driving 16 white LEDs at 15mA (eight per driver) from a 3.6V supply
- Wide input voltage range is 2.7V to 24V
- Quiescent current is 5mA typical at (VFB1 = VFB2 = 0.3V)
- Maximum duty cycle is 96% typical at (RT = 48.7K)
- Operating temperature is -40°C to 85°C
- Package style is 16-lead plastic TSSOP
