A single resistor (RSET) programs the internal master oscillator frequency, and an internal programmable divider (NDIV from 1 to 16384) sets the output frequency from 3.81 Hz to 1 MHz. The duty cycle is controlled by applying a 0 V to 1 V voltage on the MOD pin, where 0 V corresponds to 0% duty and 1 V corresponds to 100% duty (LTC6992-1 version). The output is a CMOS-level signal capable of sourcing and sinking 20 mA. The device consumes only 115 \u00b5A at 100 kHz and starts up in 500 \u00b5s.","working_principle":"The LTC6992IS6-1#TRPBF operates using a master oscillator followed by a programmable frequency divider. The master oscillator frequency is set by an external resistor RSET connected to the SET pin according to fMASTER = 1 MHz x (50 kOhm \/ RSET). The DIV pin voltage, set by a resistor divider from SET, selects one of eight divider values (NDIV = 1, 4, 16, 64, 256, 1024, 4096, 16384). The output frequency is fOUT = fMASTER \/ NDIV. The MOD pin accepts an analog voltage (0 V to 1 V) that sets the PWM duty cycle through an internal comparator and control logic. The LTC6992-1 version provides 0% to 100% duty cycle range, allowing the output to stop at extreme settings. The CMOS output stage drives rail-to-rail with 20 mA source\/sink capability. An internal voltage regulator provides supply-independent timing accuracy.","pin_description":"
