Analog Devices Inc. LTC6992MPS6-1#TRPBF

Overview

LTC6992MPS6-1#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 output with ±3.7% max duty cycle error, 3.81Hz–1MHz programmable frequency via RSET and DIV pin, and operates from 2.25V–5.5V supply across –55°C to 125°C. It serves in LED dimming, heater control, and servo loop timing where wide-duty-range analog modulation is required.

For engineers reviewing the LTC6992MPS6-1#TRPBF datasheet, LTC6992MPS6-1#TRPBF pinout, LTC6992MPS6-1#TRPBF application, or LTC6992MPS6-1#TRPBF equivalent, this page provides verified package mapping (TSOT-23-6), confirmed MOD/SET/DIV pin functions, temperature-grade validation (MP grade), and real-world design meaning for frequency accuracy, settling time, and output drive capability.

Technical Context

The LTC6992MPS6-1#TRPBF implements a master oscillator (1MHz max) whose frequency is set by ISET = VSET/RSET, where VSET is internally regulated to 1.00V ±30mV. The output frequency fOUT = 1MHz × 50kΩ / (NDIV × RSET), with NDIV selectable from 1 to 16384 via a 4-bit A/D-converter on the DIV pin.

Duty cycle is linearly controlled by VMOD from 0.1×VSET to 0.9×VSET (≈100mV–900mV), producing 0%–100% output swing; outside that range, it clamps at extremes per version. The CMOS output sources/sinks 20mA with <500µs start-up and ±1.7% max frequency error over temperature.

FAQ

What is the operating temperature range of the LTC6992MPS6-1#TRPBF?

The LTC6992MPS6-1#TRPBF is specified for continuous operation from –55°C to 125°C and is AEC-Q100 qualified for automotive applications. This extended range is validated across all electrical parameters including frequency accuracy, duty cycle error, and supply current - unlike commercial-grade variants such as LTC6992IS6-1#TRPBF, which only guarantees –40°C to 85°C.

How is the output frequency programmed on the LTC6992MPS6-1#TRPBF?

The LTC6992MPS6-1#TRPBF uses a single external resistor (RSET) connected between the SET pin and GND to program frequency. With VSET internally regulated to 1.00V, fOUT = 1MHz × 50kΩ / (NDIV × RSET), where NDIV is set by the DIV pin voltage. RSET values from 50kΩ to 800kΩ yield frequencies from 1MHz down to 3.81Hz, with ±1.7% max error over temperature.

What is the duty cycle control range and accuracy of the LTC6992MPS6-1#TRPBF?

The LTC6992MPS6-1#TRPBF supports 0% to 100% duty cycle, with linear control over VMOD = 0.1×VSET to 0.9×VSET (≈100mV–900mV). Its maximum duty cycle error is ±3.7% over –55°C to 125°C, measured at mid-scale (50% duty) and validated across RSET, NDIV, and supply voltage variations per the datasheet's Electrical Characteristics table.

Does the LTC6992MPS6-1#TRPBF require external components for basic operation?

Yes - the LTC6992MPS6-1#TRPBF requires three minimal external components for full functionality: a 0.1µF ceramic capacitor from V+ to GND, an RSET resistor from SET to GND, and a two-resistor divider on the DIV pin to select NDIV. No external crystal, PLL loop filter, or DAC is needed, enabling compact, low-cost timing solutions.

What package type and footprint does the LTC6992MPS6-1#TRPBF use?

The LTC6992MPS6-1#TRPBF uses the 6-lead Plastic TSOT-23 (S6) package - a 1mm-profile, lead-free surface-mount package with 0.95mm pitch and standard JEDEC MO-178AC outline. Pin 1 is V+, pin 2 is GND, pin 3 is SET, pin 4 is MOD, pin 5 is DIV, and pin 6 is OUT - matching the top-view pinout shown in the datasheet Rev. D, page 2.
