Taiwan Semiconductor TSCR4x Linear LED Drivers
Taiwan Semiconductor TSCR4x Linear LED Drivers are high-side Constant Current Regulators (CCRs) designed to drive LEDs in strings. These drivers feature continuous output current up to 65mA with an external resistor. These devices reduce the current at increasing temperatures to self-protect and maintain a good temperature coefficient concerning the output current. The output current at higher temperatures results from the negative temperature coefficient of -0.07%/°C of the LED driver. Taiwan Semiconductor TSCR4x LED drivers are ideally used in automotive lighting, emergency lighting, advertising, signage, decorative lighting, and retail lighting in fridges and vending machines.
