RECOM’s latest addition to its DC/DC converter portfolio is one of the smallest in its class of low profile QFN-packaged buck regulator power modules. According to the company, the RPX-2.5 module is exceptional due to its flip-chip technology which increases power density and improves thermal management.

The range and complexity of electrical equipment has increased dramatically in recent years. An unwanted consequence of this rise is the creation of harmonic currents, which can cause voltage distortion and quality problems. Here Simone Bruckner, Managing Director at Cressall Resistors, has discussed the different harmonic filter resistors that are used to combat these increasing harmonic levels.

The LM317 device from Texas Instruments is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5A over an output-voltage range of 1.25 to 37V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%.

Automotive Grade Power Metal Plate shunt resistors featuring a 20W power rating in a 3939-size package with Kelvin terminals have been introduced by Vishay Intertechnology. With their high power density, the Vishay Dale hybrid-mount WFPA3939 and WFPB3939 are designed to save space, decrease component counts, and increase measurement accuracy in automotive, industrial, and AMS applications.

Stackpole has expanded its stock of its AEC-Q200 qualified precision thin film. Available in tolerances down to ±0.01% and ±5PPM temperature coefficient, the RNCF is available in various values and case sizes. Resistance values in stock range from 24.9 ohm up to 49.9K ohm in sizes 0402, 0603, 0805, 1206, and 2512.

The INA186-Q1 from Texas Instruments is an automotive, bidirectional, low-power, voltage-output, current-sense amplifier (also called a current-shunt monitor). This device is commonly used for monitoring systems directly connected to an automotive 12V battery.

This design from Texas Instruments enables full duplex RS-485 communications over a single pair of conductors rather than four by utilising bus contention. By adding small-valued serial resistors to the bus lines to limit currents, a tri-stated differential bus is allowed and the SN65HVD96 SymPol transciver can be used to detect a state of bus contention.

This Texas Instruments design incorporates a power over coax (POC) filter network, mid-vin synchronous step-down DC/DC converter, and low-Vin power management IC (PMIC) to demonstrate a typical automotive camera power solution within an 18x18mm footprint.

The TPS23882 from Texas Instruments is an eight-channel power sourcing equipment (PSE) controller engineered to insert power onto Ethernet cables in accordance with the IEEE 802.3bt standard. The PSE controller can detect powered devices (PDs) that have a valid signature, determine the power requirements of the devices according to their classification, and apply power.

The INA191 is a low-power, voltage-output, current-shunt monitor (also called a current-sense amplifier) that is commonly used for overcurrent protection, precision-current measurement for system optimisation, or in closed-loop feedback circuits. This device can sense drops across shunts at common-mode voltages from -0.2 to +40V, independent of the supply voltage.
