LTC6992CS6-3#TRPBF

Programmable Timers And Oscillators Overview

The LTC6992CS6-3#TRPBF is a silicon oscillator and voltage-controlled pulse width modulator (PWM) from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single supply of 2.25V to 5.5V with a typical supply current of 115µA at 100kHz. The output frequency ranges from 3.81Hz to 1MHz, determined by an external resistor (RSET) and an internal programmable divider (NDIV). The duty cycle is controlled by a 0V to 1V analog input on the MOD pin. This specific variant (LTC6992-3) supports a duty cycle range of 0% to 95%. It is housed in a 6-lead Plastic TSOT-23 package and is specified for commercial temperature operation from 0°C to 70°C.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0V to 1V analog input on the MOD pin

• Internal programmable frequency divider (NDIV) with 8 settings from 1 to 16384
• Duty cycle limits of 0% minimum and 95% maximum for the -3 suffix version

Programmable Timers And Oscillators Applications

• PWM servo loops
• Heater control systems
• LED dimming control
• Portable and battery-powered equipment

Programmable Timers And Oscillators Procurement Notes

Verify the component marking L TFCQ corresponds to the LTC6992CS6-3#TRPBF part number. Confirm the package type is 6-Lead Plastic TSOT-23. Ensure the operating temperature range requirement aligns with the commercial grade specification of 0°C to 70°C. Check for RoHS compliance status as indicated in the manufacturer documentation.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992CS6-3#TRPBF when a 0% to 95% duty cycle range is required. The 'C' suffix indicates commercial temperature operation (0°C to 70°C), while 'S6' denotes the TSOT-23 package. For wider temperature ranges, consider the 'I' (-40°C to 85°C) or 'H' (-40°C to 125°C) variants. The '#TRPBF' suffix indicates tape and reel packaging.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992-1/2/3/4 family of TimerBlox silicon oscillators. The numbering suffix determines the duty cycle limits: -1 (0%-100%), -2 (5%-95%), -3 (0%-95%), and -4 (5%-100%). The CS6 designation specifies the commercial temperature grade and TSOT-23 package. Other packages include DFN (DCB) and automotive grades (MPS6, HS6/IS6 with #W suffix).

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements within the same family include LTC6992CS6-1#TRPBF, LTC6992CS6-2#TRPBF, and LTC6992CS6-4#TRPBF. Selection depends on the required duty cycle limits. For different packages, equivalent parts are available in DFN format (e.g., LTC6992CDCB-3#TRPBF).
