Description



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
