Both the TS19601 and the TS19603 requires only two resistors and two capacitors to set the output current while providing a wide range, linear, high voltage current regulator for up to 75 V in and up to 700 mA output with wide adjustment range. Dimming is possible by modulating the enable control or changing the value of the resistor. The part requires no external pass element as the power control device is integrated into the IC.
