LM3414HV Product details

Description

Power supply positive (+ve) connection Power supply negative (-ve) connection Connect to cathode of the serial LED string Connect to anode of the serial LED string PWM dimming signal input (TTL signal compatible) Connect to PTC thermal sensor for thermal foldback control Connect to PTC thermal sensor for thermal foldback control www.national.com 2 AN-2076 Connecting to LEDs and Power Supply The LM3414HV evaluation board can be powered by a DC voltage source in the range of 4.5V to 65V throug

Features

a dimming control input (DIM pin) that allows PWM dimming control. The LM3414HV is available in LLP-8 (3mm x 3mm outline) and ePSOP8 to fulfil the requirements of small solution size and high thermal performance respectively. In order to demonstrate the performance of the LM3414 family, the LM3414HV is selected for the evaluation boards because of the wide input voltage range (4.5V to 65V) providing the best flexibility to fit the requirements of different.
