Analogue / Linear / Mixed Signal ICs

With USB Power Delivery in mind, EPC has designed a 180W GaN dc-dc converter evaluation board. Its two-phase power section occupies only 24 x 24mm, using both sides of the board and ignoring input and output bulk capacitors. Called EPC91109 and intended to implement USB-PD 3.1, it delivers 12, 16 or 20V from an input range of 20 to 36V. ...

Analog Devices has created a pair of 22V stereo Class-D audio amplifier that idle at 6mA and shut-down to microamps. MAX98415A and MAX98425A are similar, and both including envelope tracking control that saves power by instructing an external dc-dc converter to provide the amplifiers main power input with just enough voltage for clean output signals. The difference between the two ...

Astute Group has signed a distribution agreement with Silanna Semiconductor to distribute its Plural ADCs in Europe and India. According to Astute, Plural ADCs offer a more affordable and versatile option with shorter lead times compared to current market alternatives. They are factory-configurable, providing over 150 ADC variants with sample rates ranging from 20 to 250Msps. The ADCs are available ...

Rohm has created a set of six current sense amplifiers with AEC-Q100 qualification for automotive use. They work with external shunt resistors, and there are two basic types: one (BD1423xFVJ-C) that can sense across the common-mode range of -14 to +80V and runs from 2.7 to 18V, and the other (BD1422xG-C) that can sense across -14 to +40V and runs ...

STMicroelectronics has made an eight-channel low-side driver for vehicles with extra functional safety hardware that “eases system-level ISO 26262 certification up to ASIL-B”, said the company. The nominal ratings of L9800, as it will be known, are: 12V power rail and 260mA per output. L9800 outputs can drive resistive, capacitive or inductive loads like relays, solenoids and LEDs,” said ST. ...

Diodes has introduced a 64Gtransfer/s PAM-4 intra-equipment range extender for PCIe 6.0 data busses, that is backwards-compatible with PCIe 5.0, 4.0 and 3.0. PI3EQX64904 is a four-differential-channel linear device with equalisation including tunable low and high-frequency and high-frequency zeros. “It optimises performance over a variety of physical media by reducing inter-symbol interference, correcting for known channel losses at the transmitter ...

Torex Semiconductor has created a nano-power dc-dc converter that can occupy only 7.7 x 3.1mm with all external capacitors – the necessary inductor is inside the device package. Called XCL108 and drawing 400nA quiescent current, it is a boost converter that will operate from inputs between 650mV and 5.5V – starting from anything above 1.6V. The device is a series, ...

Silanna Semiconductor has created a laser driver IC that can squeeze a 400W quad EEL (edge-emitting laser) module into 80mm2. SL2001 comes in a 14ball 1 x 3.5mm WLCSP (wafer-level chip-scale package) includes both a capacitor charging circuit and another block to dump that stored energy into the laser diode. Operating from a power source between 3 and 24V it ...

Analog Devices has created a fast power op-amp that can handle ±55V rails and ±1A outputs, with a digital control bus for setting internal parameters. Called ADHV4710, the output can swing ±52V with ±100mA loading, and its rails can vary down to ±12V. Despite being able to drive ±1300V/μs into 1nF, it is a voltage feedback amplifier, that can handle ...

At PCIM in Nuremberg this week, Texas Instruments announced an automotive-qualified LLC controller for light electric vehicle charging, and demonstrated it in a three-stage ac-dc battery charger for electric two-wheelers. (LLC is an inductor-inductor-capacitor topology, see diagram) “But despite the benefits that the LLC topology can offer, including minimal standby power and low audible noise, electric vehicle manufacturers have been ...
