LTC6992CS6-4#TRPBF

Programmable Timers And Oscillators Overview

The LTC6992CS6-4#TRPBF is a silicon oscillator and voltage-controlled pulse width modulator (PWM) from Analog Devices, packaged in a 6-lead Plastic TSOT-23. 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, programmed via a single resistor (RSET) and an internal divider (NDIV). The duty cycle is controlled by a 0V to 1V analog input on the MOD pin. This specific variant (LTC6992-4) supports a duty cycle range of 5% to 100%. It features CMOS outputs capable of sourcing or sinking 20mA.

Programmable Timers And Oscillators Feature Summary

Programmable Timers And Oscillators Procurement Notes

Verify the package type is TSOT-23 and the temperature grade is Commercial (0°C to 70°C). Confirm the suffix #TRPBF indicates tape and reel packaging. Ensure the -4 suffix matches the required 5% to 100% duty cycle range for the design.

Programmable Timers And Oscillators Selection Notes

Select this part when a 5% to 100% duty cycle range is required. Use LTC6992CS6-1#TRPBF for 0% to 100%, LTC6992CS6-2#TRPBF for 5% to 95%, or LTC6992CS6-3#TRPBF for 0% to 95%. Choose the CS6 package for commercial temperature range applications requiring SOT-23 form factor.

Programmable Timers And Oscillators Part Context

This component belongs to the TimerBlox family of silicon timing devices. The LTC6992 series includes four variants differentiated by their minimum and maximum duty cycle limits. The CS6 designation indicates the Commercial temperature grade (-40°C to 85°C functional, 0°C to 70°C specified) in a TSOT-23 package.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6992CS6-1#TRPBF, LTC6992CS6-2#TRPBF, and LTC6992CS6-3#TRPBF, provided the duty cycle constraints align with the application requirements.
