DC/DC Controller Uses Only a Single Inductor

The LTC3863 is a high-voltage inverting DC/DC controller that uses a single inductor to produce a negative voltage from a positive-input voltage. All of the controller’s interface signals are positive ground referenced. None of the LTC3863’s pins are connected to a negative voltage, enabling the output voltage to be limited by only the external components selection.

Operating over a 3.5-to-60-V input supply range, the LTC3863 protects against high-voltage transients, operates continuously during automotive cold crank, and covers a broad range of input sources and battery chemistries. The controller helps increase the runtime in battery-powered applications.

It has a low 70-µA quiescent current in Standby mode with the output enabled in Burst Mode operation. The LTC3863’s output voltage can be set from –0.4 to 150 V or lower at up to 3 A typical, making it well suited for 12-or-24-V automotive, heavy equipment, industrial control, telecommunications, and robotic applications.

The LTC3863 drives an external P-channel MOSFET, operates with a selectable fixed frequency between 50 and 850 kHz, and is synchronizable to an external clock from 75 to 750 kHz. Its current-mode architecture provides easy loop compensation, fast transient response, cycle-by-cycle overcurrent protection, and excellent line regulation. Output current sensing is accomplished by measuring the voltage drop across a sense resistor.
The LTC3863’s additional features include programmable soft start or tracking, overvoltage protection, short-circuit protection, and failure mode and effects analysis (FMEA) verification for adjacent pin opens and shorts.

The LTC3863 is offered in 12-pin thermally enhanced MSOP and 3-mm × 4-mm QFN packages. The controllers cost $2.06 in 1,000-unit quantities.

Digitally Tunable Capacitors for LTE Smartphones

Peregrine Semiconductor expanded its DuNE digitally tunable capacitor (DTC) product line with six second-generation devices for antenna tuning in 4G long-term evolution (LTE) smartphones. The PE623060, PE623070, PE623080, and PE623090 (PE6230x0) DTCs have a 0.6-to-7.7-pF capacitance range and support main antenna power handling of up to 34 dBm. The PE621010 and the PE621020 (PE6210x0) DTCs have a 1.38-to-14-pF capacitance range and are optimized for power handling up to 26 dBm, making them well suited for diversity antennas. The highly versatile devices support a variety of tuning circuit topologies, particularly impedance-matching and aperture-tuning applications.
The PE6230x0 DTCs are optimized for key cellular frequency bands from 700 to 2,700 MHz, featuring direct battery voltage operation with consistent performance enabled by on-chip voltage regulation.

The 5-bit, 32-state PE623060/70/80 DTCs have a 0.9-to-4.6-pF capacitance range. The 4-bit, 16-state PE623090 DTC has a 0.6-to-2.35-pF capacitance range. The PE623090 DTC’s lower minimum capacitance solves a critical problem in high-frequency tuning. The 5-bit, 32-state PE6210x0 DTCs support the 100-to-3,000-MHz frequency range. These DTCs extend the range of diversity antennas and improve data rates by optimizing the antenna performance at the operating frequency. The PE621010 DTC has a 1.38-to-5.90-pF capacitance range.

The PE6230x0 and PE6210x0 product families enable designers to develop smaller, higher-performing antennas. The product’s antenna-tuning functions—including bias generation, integrated radio frequency (RF) filtering and bypassing, control interface, and electrostatic discharge (ESD) protection of 2-kV human body model (HBM)—are incorporated into a slim, 0.55-mm × 2-mm × 2-mm package. All decoding and biasing are integrated on-chip, and no external bypassing or filtering components are required.

iC-Haus iC-TW8

The iC-TW8 is a high-resolution signal processor designed to evaluate sine/cosine sensors. Its automatic functions help minimize angular errors and jitters. The processor can be used for initial, push-button calibration and to permanently adapt signal-path parameters during operation. The angular position is calculated at a programmable resolution of up to 65,536 increments per input cycle and output as an indexed incremental signal. A 32-bit word, which includes the counted cycles, is available through the SPI.

As an application-specific DSP, the iC-TW8 has two ADCs that simultaneously sample at a 250-ksps rate, fast CORDIC algorithms, special signal filters, and an analog front end with differential programmable gate amplifier (PGA) inputs that accepts typical magnetic sensor signals from 20 mVPP and up. Signal frequencies of up to 125 kHz enable high rotary and linear speeds for position measuring devices and are processed at a 24-µs constant latency period.

The device’s 12-bit measurement accuracy works with one button press. Measuring tools are not required. The iC-TW8 independently acquires information about the signal corrections needed for offset, amplitude, and phase errors and stores them in an external EEPROM.

The iC-TW8 has two configuration modes. Preset functions and interpolation factors can be retrieved through pins and the device can be calibrated with a button push. No programming is required for initial operation.

The device’s functions—including an AB output divider for fractional interpolation, an advanced signal filter to reduce jitter, a table to compensate for signal distortion, and configurable monitors for errors and signal quality—can be accessed when the serial interfaces are used. Typical applications include magnetic linear displacement measuring systems, optical linear scales, programmable magnetic/optical incremental encoders, high-resolution absolute/incremental angle sensors with on-axis, Hall scanning, and the general evaluation of sine/cosine signals (e.g., PC measuring cards for 1 VPP and 11 µAPP).

The iC-TW8 operates on a 3.1-to-5.5-V single-ended supply within a –40°C-to-125°C extended operating temperature range. It comes in a 48-pin QFN package that requires 7 mm × 7 mm of board space. A ready-to-operate demo board is  available for evaluation. An optional PC operating program, in other words, a GUI, can be connected with a USB adapter.

The iC-TW8 costs $7.69 in 1,000-unit quantities.
