TM 7027 BuckToot TM Low-Voltage LED Power Module by LEDdynamics TM PRELIMINARY Product Overview The 7027 “BuckToot” LED Power Module is a true constantcurrent regulated driver for LEDs. Unlike standard power supplies, which deliver a fixed voltage to the output, the BuckToot LED driver is designed to reliably vary the output voltage as required to deliver a stable constant current to the LED(s). The BuckToot exhibits very high efficiency and does not require external current limiting resistors or additional heat sinking. The extremely small form-factor of the 7027 BuckToot makes it the ideal choice for many MR-11 and MR-16 integration applications since it can easily be incorporated into the housing assembly. Fully potted and sealed from harsh environments, * the BuckToot measures only 10mm diameter x 19mm long and is supplied with 150mm 24AWG colored leads. Custom sizes can be created to meet customer requirements.
