概要
Description
The LTC6994IS6-1#TRMPBF is Linear Technology (now Analog Devices) part number for the LTC6994 PWM/TIMERBLOX device. The LTC6994 is a compact, voltage-controlled PWM oscillator: you set its output frequency with a single external resistor (RSET) and its duty cycle with a control voltage. It’s used for LED dimming, motor drive, and similar applications without a microcontroller.
IS6-1 denotes a specific package/temperature variant of the device; the trailing #TRMPBF encodes packaging and compliance (Tape-and-Reel, Pb-free/machining/related packaging codes). For exact electrical specs, pinout, and application circuits, refer to the LTC6994 datasheet and TimerBlox family overview on Analog Devices’ website.

Features
Here are the key features of LTC6994IS6-1#TRMPBF (TimerBlox PWM generator):
- Fully integrated, resistor-programmable PWM with independent control of frequency and duty cycle
- Master frequency set by external RSET; duty cycle controlled via CTRL/PWM input (0%–100%)
- Single-supply operation: typically 2.25V to 5.5V; output is rail-to-rail CMOS/TTL compatible
- Industrial temperature range (typical -40°C to +125°C)
- 8-pin package; available in Tape & Reel (TR) with the IS6-1 variant designation
- Low jitter with good line/load regulation; suitable for precise PWM applications
- Small footprint and simple external-component count
- Common TimerBlox family characteristics: easy integration for LED dimming, motor control, power supplies, and related PWM tasks
Note: For exact electrical specs (master frequency range, duty-cycle resolution, input thresholds) refer to the LTC6994 datasheet.
