The SP7619 is a linear low-side, constant-current driver designed to drive high power LEDs from an input voltage rail.
The driver acts as a current source, ensuring constant LED current across a range of input voltages.
Key Features
S Very low dropout voltage (60mV@200mA) Accurate current regulation down to dropout voltage No external components Selectable output current levels: 200mA & 500mA (700mA for SP7619A) Power-saving shutdown mode of 1µA Fast turn-on (.
