LTC6992HDCB-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992HDCB-2#TRMPBF is a silicon oscillator from the TimerBlox family, featuring voltage-controlled pulse width modulation (PWM). Manufactured by Analog Devices Inc., it operates on a single 2.25V to 5.5V supply with a typical current of 115µA at 100kHz. The output frequency ranges from 3.81Hz to 1MHz, programmed via a single resistor and an internal divider. This specific variant provides a duty cycle range of 5% to 95%. It utilizes a 6-lead DFN package and supports an operating temperature range of –40°C to 125°C.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0V to 1V analog input for duty cycle adjustment
• Frequency range of 3.81Hz to 1MHz with maximum error of ±1.7%
• Duty cycle limits defined as 5% minimum and 95% maximum
• Configurable frequency divider (NDIV) from 1 to 16384

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 matches the specified H suffix for high-temperature operation (-40°C to 125°C) and the -2 suffix for the 5%-95% duty cycle window. Confirm the DCB package type corresponds to the 6-lead plastic DFN form factor. Ensure the #TRMPBF suffix indicates tape and reel packaging for surface mount assembly.

Programmable Timers And Oscillators Selection Notes

Select this part when a 5% to 95% duty cycle clamp is required to prevent oscillation stoppage at extremes. Choose the HDCB variant over CDCB or IDCB if the application demands extended industrial temperature ratings up to 125°C. Verify that the 20mA CMOS output driver capability meets the load requirements without external buffering.

Programmable Timers And Oscillators Part Context

This device belongs to the LTC6992 series, which includes four variants differentiated by their duty cycle limits: -1 (0%-100%), -2 (5%-95%), -3 (0%-95%), and -4 (5%-100%). The HDCB designation specifically identifies the high-temperature grade housed in the 2mm x 3mm DFN package.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes within the same family include LTC6992HDCB-1#TRMPBF, LTC6992HDCB-3#TRMPBF, and LTC6992HDCB-4#TRMPBF. Selection among these depends strictly on the required minimum and maximum duty cycle constraints for the specific application.
