Product details
Overview
LTC6992HDCB-1#TRPBF from Analog Devices is a voltage-controlled pulse width modulator (PWM) IC in the TimerBlox family, designed for precision analog duty cycle control. It delivers 0% to 100% PWM range, operates from 2.25V to 5.5V, achieves ±1.7% max frequency error over –40°C to 125°C, and uses a single RSET resistor to program output frequencies from 3.81Hz to 1MHz - ideal for LED dimming and heater control in automotive under-hood environments.
For engineers reviewing the LTC6992HDCB-1#TRPBF datasheet, LTC6992HDCB-1#TRPBF pinout, LTC6992HDCB-1#TRPBF application, or LTC6992HDCB-1#TRPBF equivalent, this page provides verified package mapping (6-lead DFN), confirmed MOD/SET/DIV pin functions, duty-cycle linearity data at 0–100%, and validated alternatives for high-temp PWM timing replacement.
Technical Context
The LTC6992HDCB-1#TRPBF integrates a master oscillator (1MHz max) with a programmable divider (NDIV = 1, 4, 16…16384) and an analog PWM modulator where VMOD input (0.1×VSET to 0.9×VSET) linearly sets duty cycle. Its internal 1V SET-regulator enables RSET-based frequency programming independent of V+ drift.
It features a 4-bit A/D converter on the DIV pin for NDIV and polarity selection, CMOS output capable of ±20mA, and built-in power-on reset with 500µs startup time. The device is qualified to AEC-Q100 Grade H (–40°C to 125°C) and supports stable operation with ≤10pF capacitance on SET and ≤100pF on DIV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 3.81Hz to 1MHz - set by RSET (50kΩ–800kΩ) and NDIV; enables ultra-low-power sleep-mode timing or high-speed LED modulation. |
| Duty Cycle Range | 0% to 100% - full-range modulation allows output halt at extremes; supports servo stop and zero-power states. |
| Frequency Accuracy | ±1.7% max over –40°C to 125°C - ensures reliable timing without external calibration in automotive engine control units. |
| Supply Voltage | 2.25V to 5.5V - compatible with Li-ion battery systems and 3.3V/5V industrial rails without level-shifting. |
| Supply Current | 105µA to 450µA - scales with NDIV and RSET; enables <120µA operation at 16384× division for low-duty-cycle wake-up timers. |
| Output Drive | ±20mA CMOS - directly drives LEDs, small solenoids, or logic inputs without external buffers. |
| Operating Temp | –40°C to 125°C - qualified per AEC-Q100 H-grade; validated for under-hood automotive and industrial motor control. |
Pinout & Package
Package: 6-lead (2mm × 3mm) plastic DFN (DCB), exposed pad (Pin 7) tied to GND; suitable for high-density PCB layouts and thermal management in compact modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 6) | Digital PWM output | CMOS rail-to-rail output (GND to V+) with 30Ω typical drive impedance; sources/sinks 20mA; requires series resistor for low-Z loads. |
| GND (Pin 2) | Analog/digital ground reference | Low-inductance return path for SET, MOD, and output; exposed pad must be connected to PCB ground plane for thermal and noise performance. |
| SET (Pin 3) | Frequency-setting input | Internally regulated to 1.00V ±30mV; ISET = VSET/RSET programs master oscillator; ≤10pF capacitance required for stability. |
| V+ (Pin 1) | Power supply input | 2.25V–5.5V operation; bypass with 0.1µF ceramic capacitor directly to GND; noise-sensitive node affecting jitter and accuracy. |
| DIV (Pin 4) | Divider ratio & polarity select | 4-bit A/D input referenced to V+; resistor divider sets NDIV (1–16384) and POL bit; ≤100pF capacitance ensures fast settling. |
| MOD (Pin 5) | Analog PWM control input | 0.1×VSET to 0.9×VSET (≈100mV–900mV) linearly controls duty cycle; clamps at 0%/100% for full-range LTC6992-1 variant. |
Key Features
| Feature | Design Value |
|---|---|
| Single-resistor frequency programming | RSET (50kΩ–800kΩ) sets fOUT without trimming or calibration; eliminates need for DACs or microcontroller timing loops. |
| 0%–100% analog PWM control | Full-range duty cycle enables true output disable (0%) and continuous conduction (100%), critical for safety-critical shutdowns. |
| AEC-Q100 Grade H qualification | Validated for –40°C to 125°C operation with long-term drift ≤90ppm/√kHr - meets automotive engine bay reliability requirements. |
| Low quiescent current scaling | Current drops to 105µA at high NDIV and large RSET - extends battery life in always-on sensor nodes and wake-up timers. |
| Integrated 4-bit DIV A/D converter | Eliminates external ADC or digital interface; resistor-divider programming of NDIV and polarity simplifies BOM and layout. |
Applications
| LED Dimming Control | Heater Power Regulation |
|---|---|
|
Use Scenario: Precise brightness control of automotive cabin LEDs across wide temperature ranges. IC Role / Device Role / Timing Role: Voltage-controlled PWM generator providing analog-set dimming signals to LED drivers. Use Value: 0%–100% duty cycle enables full off-state and maximum intensity; ±1.7% frequency accuracy prevents visible flicker at 1kHz+ switching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-controlled PWM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6992HDCB-2#TRPBF | 5%–95% duty cycle range; tighter min/max clamping prevents full on/off states. | Suitable where output must never fully disable or saturate - e.g., fan control requiring minimum airflow. | Select when system safety requires guaranteed minimum/maximum conduction; not drop-in for 0%/100% use cases. |
| LTC6992HS6-1#TRPBF | Same functionality but in TSOT-23 package (6-lead); higher θJA (192°C/W); identical electrical specs. | Better suited for space-constrained prototypes or low-volume designs where DFN reflow is unavailable. | Choose for manual assembly or legacy SMT lines; verify thermal derating due to lower power dissipation capability. |
Compared with LTC6992HDCB-1#TRPBF, the -2 variant trades full-range modulation for improved duty-cycle repeatability near limits, while the HS6-1 offers identical timing performance in a smaller footprint at the cost of thermal margin - both require board-level validation for thermal and layout integrity.

FAQ
What is the operating temperature range for the LTC6992HDCB-1#TRPBF?
The LTC6992HDCB-1#TRPBF is rated for –40°C to 125°C operation and qualified to AEC-Q100 Grade H. This specification is guaranteed across the full range, making it suitable for under-hood automotive applications and industrial environments with extreme thermal cycling. Electrical parameters including frequency accuracy (±1.7% max) and duty cycle error (<3.7% max) are specified over this entire interval.
How do I configure the output frequency of the LTC6992HDCB-1#TRPBF?
You configure the output frequency of the LTC6992HDCB-1#TRPBF using two elements: a resistor RSET (50kΩ–800kΩ) between SET and GND to set the master oscillator frequency, and a resistor divider on the DIV pin to select NDIV (1, 4, 16…16384). The final fOUT = 1MHz × 50kΩ / (NDIV × RSET). For example, RSET = 200kΩ and DIVCODE = 4 (NDIV = 16) yields fOUT = 1.5625kHz.
Does the LTC6992HDCB-1#TRPBF support 0% and 100% duty cycle output?
Yes - the LTC6992HDCB-1#TRPBF is the -1 variant, explicitly specified for 0% to 100% duty cycle range. When VMOD ≤ 0.1×VSET, output halts (0%); when VMOD ≥ 0.9×VSET, output remains continuously high (100%). This full-range behavior is confirmed in the device's ordering matrix and electrical characteristics table under DMIN = 0% and DMAX = 100%.
What package type does the LTC6992HDCB-1#TRPBF use?
The LTC6992HDCB-1#TRPBF uses a 6-lead (2mm × 3mm) plastic DFN package designated DCB, with an exposed thermal pad (Pin 7) that must be connected to the PCB ground plane. This package is distinct from the TSOT-23 option (S6) and offers superior thermal performance (θJA = 64°C/W) and board-level robustness for high-vibration applications.
Can the LTC6992HDCB-1#TRPBF replace a microcontroller-based PWM generator?
Yes - the LTC6992HDCB-1#TRPBF replaces MCU-based PWM in applications requiring deterministic, low-jitter, analog-controlled timing without firmware overhead. Its 500µs startup, ±20mA drive, and 0%–100% range enable direct substitution in LED dimming, heater control, and servo loops - provided the system only needs one PWM channel and analog voltage modulation rather than digital register access.
