LTC6992CS6-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992CS6-1#TRMPBF is a voltage-controlled pulse width modulator from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single 2.25V to 5.5V supply with a typical current consumption of 115µA at 100kHz. The device generates PWM signals with frequencies ranging from 3.81Hz to 1MHz, determined by an external resistor (RSET) and an internal programmable divider (NDIV). Duty cycle is controlled via a 0V to 1V analog input on the MOD pin, offering a range of 0% to 100% for the -1 variant. It features a CMOS output capable of sourcing or sinking 20mA and is housed in a 6-lead TSOT-23 package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates a tape and reel mini-packaging format containing 500 units. Confirm the 'C' grade corresponds to the 0°C to 70°C specified temperature range. Ensure the 'S6' designation matches the required 6-lead TSOT-23 package for the target PCB layout. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability status.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992CS6-1 variant specifically for applications requiring a full 0% to 100% duty cycle range. The 'C' grade is suitable for commercial environments operating between 0°C and 70°C. For wider temperature ranges, consider the 'I', 'H', or 'MP' grades. The S6 package is appropriate for space-constrained surface-mount designs. Verify that the required frequency accuracy and jitter specifications meet the system requirements.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 series of silicon oscillators within the TimerBlox family. The base model supports four duty cycle variants (-1, -2, -3, -4), with the -1 version providing the widest modulation range. The CS6-1 designation specifies the commercial temperature grade, TSOT-23 package, and 0-100% duty cycle capability. It is designed as a drop-in replacement for discrete PWM generation circuits.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes include other parts from the LTC6992 family with different temperature grades or duty cycle limits, such as LTC6992IS6-1 or LTC6992HS6-1. Ensure any replacement matches the 6-lead TSOT-23 footprint and electrical characteristics, particularly supply voltage and output drive current.
