FEATURES
• The new driver incorporates a Pulse Current Drive Mode that raises efficiency over 90% while driving up to six white LEDs in a serial connection.
• In Direct Current Drive Mode white LEDs can be driven with very low noise and efficiencies over 85%.
• The TB62731FU uses bi-cadmium (BiCD) process technology. This new methodology allows for a reduction in the external component count therefore lowering costs and improving battery life.
• Newly developed temperature derating technology predicts environmental temperature, including heat dissipating from the driver IC itself, and adjusts current to optimize light emission.
• Ultra compact 6-pin SOT23 package.
• Ability to drive all wavelengths and materials.
• +3.0V to +5.5V supply voltage
• Adjustable output current (Up to 320mW output power) 20mA driving current can be supply for LEDs with 16V total Vf
• Internal switching MOSFET (1.5 ohm typ)
• Shutdown function
