LTC6992HDCB-3#TRPBF

Programmable Timers And Oscillators Overview

The LTC6992HDCB-3#TRPBF is a silicon oscillator featuring voltage-controlled pulse width modulation (PWM) from Analog Devices. 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 and internal divider. This specific variant provides a PWM duty cycle range of 0% to 95%. It is housed in 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 via 0V to 1V analog input
• Frequency range: 3.81Hz to 1MHz
• Duty cycle limits: 0% minimum, 95% maximum
• Low supply current: 115µA at 100kHz

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 ordering suffix #TRPBF indicates tape and reel packaging. Confirm the HDCB designation corresponds to the 6-lead plastic DFN package. Ensure the -3 suffix matches the required 0% to 95% duty cycle constraints for the design. Check automotive qualification requirements if applicable, as standard versions differ from W-suffix automotive grades.

Programmable Timers And Oscillators Selection Notes

Select this part when a 0% to 95% duty cycle window is sufficient. Use the LTC6992-1 or -4 variants if 100% duty cycle is required. Choose the HDCB package for compact surface-mount layouts. Verify that the RSET resistor tolerance meets the ±1.7% frequency accuracy requirement over the specified temperature range.

Programmable Timers And Oscillators Part Context

This component belongs to the TimerBlox family of versatile silicon timing devices. The LTC6992 series includes four variants distinguished by their duty cycle limits. The -3 version specifically allows oscillation to stop at 0% but clamps at 95%, differentiating it from the -1 (0-100%), -2 (5-95%), and -4 (5-100%) models.

Programmable Timers And Oscillators Replacement Considerations

LTC6992IDCB-3#TRPBF offers identical electrical specifications with an extended industrial temperature range of –40°C to 85°C. LTC6992CDCB-3#TRPBF provides the same function within a commercial range of 0°C to 70°C. Package alternatives include the SOT-23-6 format, such as LTC6992HS6-3#TRPBF.
