Linear Constant Current Regulated LED Driver DESCRIPTION FEATURES
The TSCR400 & TSCR402 are High-Side Constant ● LED drive current preset: Current Regulator (CCR) for linear LED driving. The ● TSCR400CX6: 0.1mA device regulates with a preset TSCR400 0.1mA and ● TSCR402CX6: 20mA TSCR402 20mA nominal that can be adjusted with an ● Continuous output current up to 65mA with an external resistor up to 65mA. It is designed for driving external resistor LEDs in strings and will reduce current at increasing ● Easy paralleling of drivers to increase current temperatures to self-protect. Operating as a series ● Supply voltage up to 40V linear CCR for LED string current control, it can be ● Good temperature coefficient vs. output current used in multiple applications, as long as the maximum ● Compliant to RoHS Directive 2011/65/EU and in supply voltage to the device is <40V. accordance to WEEE 2002/96/EC. The output current at higher temperatures is the result ● Halogen-Free according to IEC 61249-2-21 of the negative temperature coefficient of -0.07%/°C of
