Product details
Overview
LTC6992IDCB-1#TRPBF from Analog Devices is a voltage-controlled pulse width modulator (PWM) IC in the TimerBlox family, designed for precise analog-digital timing control. It delivers 0% to 100% duty cycle range, programmable output frequency from 3.81 Hz to 1 MHz via RSET and DIV pin, and operates from 2.25 V to 5.5 V supply. It is used in LED dimming, heater control, and servo loop applications requiring stable, low-jitter PWM generation.
For engineers reviewing the LTC6992IDCB-1#TRPBF datasheet, LTC6992IDCB-1#TRPBF pinout, LTC6992IDCB-1#TRPBF application, or LTC6992IDCB-1#TRPBF equivalent, this device offers verified 6-pin DFN packaging, guaranteed –40°C to +85°C industrial temperature operation, <1.7% frequency error, <3.7% PWM duty cycle error, and CMOS output capable of ±20 mA drive - critical for precision analog-controlled power stages.
Technical Context
The LTC6992IDCB-1#TRPBF integrates a master oscillator with 1 MHz base frequency, regulated SET pin (VSET = 1.00 V ±30 mV), and a 4-bit A/D converter on the DIV pin to select NDIV values (1, 4, 16, ..., 16384). Its internal PWM core maps MOD pin voltage (0.1×VSET to 0.9×VSET) linearly to output duty cycle without external compensation.
It features built-in power-on reset, 500 µs startup time, and digital filtering to suppress noise-induced duty cycle jitter. The device supports polarity inversion via POL bit (MSB of DIVCODE) and halts oscillation when ISET falls below ~500 nA - enabling safe disable functionality in fault conditions.
Key Specifications

Pinout & Package
Package: 6-lead (2 mm × 3 mm) plastic DFN (DCB), 1 mm profile, exposed pad (GND), RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Accepts 2.25–5.5 V; requires local 0.1 µF bypass to GND for low-noise operation and jitter suppression. |
| DIV | Programmable divider & polarity input | 4-bit A/D input; resistor-divider voltage sets NDIV (1–16384) and output polarity (POL bit); ≤100 pF capacitance required. |
| SET | Frequency-setting reference node | Internally regulated at 1.00 V; connects to GND via RSET (50 kΩ–800 kΩ) to set master oscillator frequency. |
| MOD | Analog PWM control input | 0.1×VSET to 0.9×VSET (≈100–900 mV) linearly controls duty cycle; clamps at 0%/100% extremes for LTC6992-1. |
| GND | Ground reference | Low-inductance connection point for all bypass caps and load return paths; tied to exposed pad for thermal performance. |
| OUT | CMOS PWM output | Rail-to-rail swing (GND to V+); 30 Ω typical output resistance; ±20 mA drive supports direct LED/relay/FET gate driving. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM | 0.1 V to 0.9 V analog input directly maps to 0–100% duty cycle - eliminates microcontroller PWM peripherals and DACs. |

FAQ
What is the operating temperature range for LTC6992IDCB-1#TRPBF?
The LTC6992IDCB-1#TRPBF is specified for industrial operation from –40°C to +85°C. This range is fully tested and guaranteed per the datasheet's "Specified Temperature Range" table for the "I" grade. It does not carry AEC-Q100 qualification, unlike certain automotive variants (e.g., #W suffix parts), and is intended for non-automotive industrial environments.
How do I set the output frequency of LTC6992IDCB-1#TRPBF?
The output frequency of LTC6992IDCB-1#TRPBF is set by two elements: an external RSET resistor from SET to GND (50 kΩ to 800 kΩ), and the voltage applied to the DIV pin, which selects NDIV (1 to 16384). The formula is fOUT = (1 MHz × 50 kΩ) / (NDIV × RSET). For example, RSET = 200 kΩ and DIV = 0.25×V+ yields NDIV = 4 and fOUT = 62.5 Hz.
Does LTC6992IDCB-1#TRPBF support 0% and 100% duty cycle?
Yes - LTC6992IDCB-1#TRPBF is the -1 variant, explicitly supporting 0% to 100% duty cycle. When VMOD ≤ 0.1×VSET, output stops (0% duty); when VMOD ≥ 0.9×VSET, output is fully on (100% duty). This behavior is confirmed in the "DEVICE NAME / PWM DUTY CYCLE RANGE" table and applies across its full temperature and supply range.
What is the maximum output drive capability of LTC6992IDCB-1#TRPBF?
The LTC6992IDCB-1#TRPBF provides rail-to-rail CMOS output with ±20 mA drive strength at V+ = 2.25 V to 5.5 V. VOH is ≥4.84 V at V+ = 5.5 V and IOUT = –16 mA; VOL is ≤0.54 V at same conditions. This allows direct driving of small LEDs, logic inputs, or MOSFET gates without external buffers - verified in the "Digital Output" section of the datasheet.
Can LTC6992IDCB-1#TRPBF be used with a 2.5 V supply?
Yes - LTC6992IDCB-1#TRPBF operates down to 2.25 V, making 2.5 V fully supported. At 2.5 V, supply current drops to 215–265 µA (depending on NDIV and RSET), and output swing remains rail-to-rail (0 V to 2.5 V) with VOL ≤0.26 V and VOH ≥2.17 V at rated load. All key specs including frequency accuracy and duty cycle error remain valid per the "l"-marked rows in Electrical Characteristics.
