LTC6992HDCB-1#TRPBF

Programmable Timers And Oscillators Overview

The LTC6992HDCB-1#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 365µA at 100kHz. The output frequency ranges from 3.81Hz to 1MHz, programmed via a single resistor RSET and an internal divider NDIV selectable from 1 to 16384. Duty cycle is controlled by a 0V to 1V analog input on the MOD pin, offering a 0% to 100% range for the -1 variant. It provides a CMOS output capable of sourcing/sinking 20mA and is housed in a 6-lead DFN package.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0% to 100% duty cycle range
• Frequency range of 3.81Hz to 1MHz using 1 to 3 resistors
• Low supply current: 115µA typ at 100kHz, 365µA max at 100kHz
• CMOS output driver sources/sinks 20mA

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 specific suffix #TRPBF indicates tape and reel packaging. Confirm the 'H' grade corresponds to the –40°C to 125°C operating temperature range. Ensure the 'DCB' package matches the 6-lead 2mm × 3mm plastic DFN requirement. Cross-reference the '-1' designation for the 0% to 100% duty cycle limit against system requirements.

Programmable Timers And Oscillators Selection Notes

Select this part when a wide 0% to 100% duty cycle range is required. The H-grade version supports industrial temperatures up to 125°C. Frequency accuracy is ±1.7% maximum over temperature. Use precision resistors for RSET to minimize frequency error. The DIV pin allows programmable division ratios from 1 to 16384.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 series, which includes variants -1, -2, -3, and -4 differing primarily in duty cycle limits. The HDCB suffix denotes the high-temperature (-40°C to 125°C) DFN package. Other packages include SOT-23 (S6). Automotive versions are available with the #W suffix.

Programmable Timers And Oscillators Replacement Considerations

LTC6992IDCB-1#TRPBF offers the same electrical specifications but with a commercial temperature range of –40°C to 85°C instead of the industrial –40°C to 125°C range.
