TSCR420CX6H / TSCR421CX6H Taiwan Semiconductor Linear Constant Current Regulated LED Driver DESCRIPTION FEATURES The TSCR420 & TSCR421 are Low-Side Constant Current Regulator (CCR) for linear LED driving. The device regulates with a preset 10mA nominal that can be adjusted with an external resistor up to 300mA. It is designed for driving LEDs in strings and will reduce ● AEC-Q100 qualified with the following results: Device temperature grade 1: -40°C to 125°C Device HBM ESD classification level H2 Device CDM ESD classification level C6 ● LED drive current preset to 10mA ● Continuous output current up to 300mA with an external resistor ● Very low enable current ● Easy paralleling of drivers to increase current ● Supply voltage up to 40V ● Digital PWM input up to 10kHz (TSCR421) ● Good temperature coefficient vs. output current ● Compliant to RoHS Directive 2011/65/EU and in accordance to WEEE 2002/96/EC. ● Halogen-Free according to IEC 61249-2-21 current at increasing temperatures to self-protect. Operating as a series linear CCR for LED string current control, it can be used in multiple applications, as long as the maximum supply voltage to the device is <40V. With the low-side control, the TSCR421 has an Enable (EN) pin which can be pulse-width modulated (PWM) up to 10kHz by a microcontroller for LED dimming. The output current at higher temperatures is the result of the negative temperature coefficient of 0.07%/°C of the LED driver.
