The TSCR400 & TSCR402 from Taiwan Semiconductor are high-side constant current regulators (CCR) for linear LED driving. TSCR400 and TSCR402 regulate with presets of 0.1mA and 20mA nominal (respectively) that are adjustable with an external resistor up to 65mA. Taiwan Semiconductor designed them to drive LEDs in strings, and they will reduce current at increasing …
