Product details
Overview
LTC6992CS6-3#TRPBF from Analog Devices is a voltage-controlled pulse width modulator (PWM) IC in the TimerBlox family, configured for 0% to 95% duty cycle range. It operates from 2.25V to 5.5V, delivers CMOS output with ±20mA drive, and achieves frequency accuracy of ±1.7% over temperature using a single RSET resistor. It is used in LED dimming control where precise analog-voltage-based duty cycle adjustment is required.
For engineers reviewing the LTC6992CS6-3#TRPBF datasheet, LTC6992CS6-3#TRPBF pinout, LTC6992CS6-3#TRPBF application, or LTC6992CS6-3#TRPBF equivalent, this page provides verified specifications, SOT-23-6 package details, duty-cycle-limited PWM functionality, and validated automotive-grade alternatives for thermal-stable timing control in portable and high-vibration environments.
Technical Context
The LTC6992CS6-3#TRPBF implements a master oscillator (1MHz max) with programmable division (NDIV = 1, 4, 16…16384) and analog voltage-to-duty-cycle conversion via the MOD pin (0V–1V input). Its internal 4-bit A/D converter on the DIV pin selects both NDIV and polarity (POL), while the SET pin regulates VSET to 1.00V ±30mV for stable frequency programming.
It features built-in power-on reset, 500µs startup time, and output clamping at 0% or 95% duty cycle-matching the LTC6992-3 variant's defined limits. The device maintains <3.7% PWM duty cycle error across its full operating range (–40°C to 85°C) and supports long-term stability of 90ppm/√kHr.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 3.81Hz to 1MHz - enables low-speed motor control and high-frequency LED switching without external clock sources. |
| Duty Cycle Range | 0% to 95% - supports full-off capability and avoids 100% conduction in safety-critical dimming or heater control. |
| Frequency Accuracy | ±1.7% max over temperature - ensures predictable timing without calibration in industrial ambient conditions. |
| Supply Current | 105–450µA - scales with NDIV and RSET, enabling ultra-low-power operation in battery-powered systems. |
| Operating Temperature | –40°C to 85°C - qualified for commercial and extended-temperature embedded applications including automotive cabin electronics. |
| Output Drive | ±20mA CMOS - directly drives LEDs, small MOSFET gates, or logic inputs without external buffers. |
| MOD Input Range | 0.1×VSET to 0.9×VSET (≈100mV–900mV) - linear analog control region with clamped endpoints for deterministic behavior. |
Pinout & Package
Package: 6-lead TSOT-23 (S6), 1mm profile, lead-free, RoHS-compliant. Exposed pad not present in S6 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | 2.25V–5.5V rail; requires local 0.1µF bypass to GND for noise immunity and stable oscillation. |
| DIV | Programmable divider & polarity select | 4-bit A/D input; resistor-divider voltage sets NDIV (1–16384) and output polarity (POL bit). |
| SET | Frequency-setting node | Internally regulated to 1.00V; current ISET = VSET/RSET determines master oscillator frequency. |
| MOD | Analog PWM control input | 0V–1V input maps linearly to 0%–95% duty cycle; clamps outside 0.1×VSET–0.9×VSET range. |
| GND | Ground reference | Low-inductance connection point for all bypass caps and signal returns; ties to exposed pad in DFN variants (not applicable here). |
| OUT | PWM output driver | CMOS rail-to-rail output; sources/sinks up to ±20mA; rise/fall times ≤2.7ns at V+ = 2.25V. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM | 0V–1V analog input directly sets duty cycle with <3.7% error - eliminates need for microcontroller PWM peripherals or DACs. |
| Single-resistor frequency setting | RSET (50kΩ–800kΩ) programs fOUT from 3.81Hz–1MHz - simplifies BOM and layout vs crystal + divider solutions. |
| Configurable output polarity | POL bit (via DIV pin) inverts duty cycle response - supports active-low gate drivers or inverted control logic without external inverters. |
| Ultra-low quiescent current | 105µA min at V+ = 2.25V, RSET = 800kΩ, NDIV ≥16 - extends battery life in always-on sensor nodes or wearables. |
| Robust start-up behavior | 500µs guaranteed start-up time with POR - ensures reliable initialization after brown-out or cold start. |

FAQ
What is the duty cycle range supported by the LTC6992CS6-3#TRPBF?
The LTC6992CS6-3#TRPBF is the LTC6992-3 variant and supports a 0% to 95% duty cycle range. When the MOD pin voltage falls below ~0.1×VSET, output stops (0% duty); above ~0.9×VSET, it clamps at 95%. This range is fixed per part number and cannot be altered by external configuration.
How do I set the output frequency of the LTC6992CS6-3#TRPBF?
The output frequency of the LTC6992CS6-3#TRPBF is set using a single resistor (RSET) between the SET pin and GND. With RSET = 50kΩ–800kΩ, fOUT = 1MHz × 50kΩ / (NDIV × RSET), where NDIV is selected via the DIV pin voltage. Typical design uses two resistors (R1/R2) on DIV to select NDIV = 1, 4, 16, etc.
Does the LTC6992CS6-3#TRPBF require an external crystal or resonator?
No, the LTC6992CS6-3#TRPBF is a fully integrated silicon oscillator and does not require any external crystal, resonator, or capacitor for basic operation. Its timing core is monolithic and factory-trimmed - only RSET and optional DIV resistors are needed for frequency and division setup.
What is the maximum output drive capability of the LTC6992CS6-3#TRPBF?
The LTC6992CS6-3#TRPBF provides a CMOS output capable of sourcing and sinking up to ±20mA at V+ = 2.25V–5.5V. VOH remains ≥2.17V and VOL ≤0.26V under full load, enabling direct interface with logic inputs, small MOSFET gates, or LED strings with series current-limiting resistors.
Is the LTC6992CS6-3#TRPBF qualified for automotive applications?
The LTC6992CS6-3#TRPBF is not AEC-Q100 qualified. For automotive use, Analog Devices offers the LTC6992IS6-3#WTRPBF (AEC-Q100 Grade 3) and LTC6992HS6-3#WTRPBF (Grade 1), which undergo controlled manufacturing and reliability testing per automotive standards - these are the recommended alternatives for vehicle subsystems.
