Analog Linearized 3-Wire PT100 RTD to 2-Wire 4-20mA Current Loop Transmitter Reference Design
TIPD161: This design features a single-chip solution to linearize and transmit a 3-wire PT100 RTD over the industry standard 2-wire 4-20mA current loop. The design was configured for a -200°C to 800°C temperature range, but other temperature ranges can be achieved by adjusting the component values as discussed in the Theory of Operation section of the reference design guide.
230V, 900W, Power Factor Regulator Conv (PFC) for Inverter Fed Drives in Appliances Reference Design
TIDA-00443: TIDA-00443 is a 900W power factor regulator converter designed for inverter fed BLDC/PMSM motor based appliances. This reference design is a continuous conduction mode boost converter implemented using UCC28180 PFC controller and with all the necessary protections built-in. The design supports a wide AC input range from 195 VAC to 270 VAC and offers very high efficiency of >97%, over wide operating loads from 50% to 100%. The boost follower configuration utilized in TIDA-00443 aids in reducing switching losses in the PFC regulator as well as in downstream inverter/converter. This reference design delivers an efficiency of ~98%, in boost follower configuration. In comparison to fixed voltage operation, this boost follower configuration saves an additional power of 5.2 W at 230 VAC and full load. TIDA-00443 has been designed to meet the IEC-61000-2-3 iTHD limits of both Class A and Class D norms. In addition the design improves overall system performance with lower bus ripple, lower bus capacitance, lower RMS currents, and built-in front end protections. Hardware is designed and tested to pass conducted emissions, surge, and EFT as per EN55014 requirements for household appliances.
85VAC-265VAC Input, 24V@0.1A Non-Isolated Flyback
PMP4043: This reference design uses the UCC28600 quasi-resonant flyback controller to generate a 24V/0.1A output from a universal AC input source. This flyback converter is not isolated. Three transistors are used in place of an opto-coupler to reduce the overall BOM cost.
Analog Linearized 3-Wire PT1000 RTD to 2-Wire 4-20mA Current Loop Transmitter Reference Design
TIPD202: This design features a single-chip solution to linearize and transmit a 3-wire PT1000 RTD over the industry standard 2-wire 4-20mA current loop. The design was configured for a -50°C to 250°C temperature range, but other temperature ranges can be achieved by adjusting the component values as discussed in the Theory of Operation section of the reference design guide. Unadjusted design accuracy was measured to be less than 0.15°C over the selected RTD temperature span.
