LTC6992HDCB-2#TRPBF

Programmable Timers And Oscillators Overview

The LTC6992HDCB-2#TRPBF is a silicon oscillator featuring voltage-controlled pulse width modulation (PWM) from the TimerBlox family. Manufactured by Analog Devices, 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, determined by an external resistor and internal divider. This specific variant provides a duty cycle range of 5% to 95%, controlled by a 0V to 1V analog input on the MOD pin. It utilizes a 6-lead DFN package and supports an operating temperature range of –40°C to 125°C.

Programmable Timers And Oscillators Procurement Notes

Verify the component matches the specified H grade for high-temperature operation (-40°C to 125°C). Confirm the DCB package type and TRPBF tape-and-reel packaging. Ensure the -2 suffix corresponds to the required 5%-95% duty cycle window for the design.

Programmable Timers And Oscillators Selection Notes

Select this part when a 5% to 95% duty cycle limit is necessary to prevent oscillation stoppage at extremes. Compare against -1 (0-100%), -3 (0-95%), and -4 (5-100%) variants based on application requirements. Ensure the DIV pin resistor network correctly sets the desired frequency division ratio.

Programmable Timers And Oscillators Part Context

This device belongs to the LTC6992 series of TimerBlox silicon oscillators. The HDCB designation indicates the H temperature grade and the DCB plastic DFN package. The #TRPBF suffix denotes a lead-free finish in a tape-and-reel configuration suitable for automated surface-mount assembly.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes within the same family include LTC6992IDCB-2#TRPBF (industrial temp) or LTC6992CDCB-2#TRPBF (commercial temp), provided the temperature range meets system needs. Other suffixes like S6 indicate TSOT-23 packaging.
