LTC6992CDCB-3#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992CDCB-3#TRMPBF 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 via a 0V to 1V analog input on the MOD pin. This specific variant, the -3 version, supports a duty cycle range of 0% to 95%. It is housed in a 6-lead DFN package and is specified for commercial temperature operation from 0°C to 70°C.

Programmable Timers And Oscillators Feature Summary

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix #TRMPBF indicates a mini tape and reel packaging format containing 500 units. Confirm the 'C' grade designation aligns with the required 0°C to 70°C operating temperature range for the application environment. Ensure the DCB package type matches the PCB footprint design specifications.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992CDCB-3#TRMPBF when a 0% to 95% duty cycle window is required. The 'C' suffix denotes commercial temperature performance (0°C to 70°C), while the 'DCB' indicates the 2mm x 3mm DFN package. Verify that the RSET resistor tolerance meets the desired frequency accuracy requirements, as the device guarantees ±1.7% maximum frequency error.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992-1/2/3/4 family of TimerBlox silicon oscillators. The '-3' suffix specifically defines the duty cycle clamp characteristics, allowing a minimum of 0% but limiting the maximum to 95%, distinguishing it from the -1 (0-100%), -2 (5-95%), and -4 (5-100%) variants within the same series.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes include other members of the LTC6992 family such as the LTC6992CDCB-1#TRMPBF or LTC6992CDCB-2#TRMPBF, provided the duty cycle limits are acceptable. Alternative packages like the SOT-23-6 (CS6 suffix) may be used if pin compatibility and thermal requirements are verified.
