LTC6992CDCB-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992CDCB-2#TRMPBF is a silicon oscillator featuring voltage-controlled pulse width modulation (PWM). It generates PWM signals with frequencies ranging from 3.81 Hz to 1 MHz, determined by an external resistor on the SET pin and an internal divider. Duty cycle is controlled via a 0V to 1V analog input on the MOD pin. This specific variant provides a duty cycle range of 5% to 95%. It operates on a single supply voltage between 2.25 V and 5.5 V, drawing approximately 115 µA at 100 kHz. The device 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

• Voltage-controlled PWM output with 5% to 95% duty cycle limits
• Frequency range of 3.81 Hz to 1 MHz using a single external resistor
• Low supply current of 115 µA at 100 kHz
• CMOS output driver capable of sourcing/sinking 20 mA

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 #TRMPBF indicates a mini tape and reel packaging format containing 500 units. Confirm the DCB package designation corresponds to the 6-lead (2mm × 3mm) plastic DFN form factor. Ensure the C grade specification aligns with the required 0°C to 70°C operating temperature range for the target application environment.

Programmable Timers And Oscillators Selection Notes

Select this part when a 5% to 95% duty cycle window is required, as other variants offer 0% or 100% extremes. The CDCB suffix denotes the commercial temperature grade; use IDCB or HDCB suffixes if operation below 0°C or above 70°C is necessary. Verify that the 2mm × 3mm DFN footprint fits the PCB layout constraints compared to the SOT-23 alternative.

Programmable Timers And Oscillators Part Context

This component belongs to the TimerBlox family of silicon timing devices manufactured by Analog Devices Inc. The LTC6992 series includes four distinct models (-1 through -4) differentiated primarily by their minimum and maximum duty cycle clamping behaviors. The -2 variant specifically restricts the output duty cycle to prevent full off or full on states under extreme analog input conditions.

Programmable Timers And Oscillators Replacement Considerations

LTC6992IDCB-2#TRMPBF offers identical electrical performance but supports an extended industrial temperature range of –40°C to 85°C.
