productroundup Signal conditioning for magnetoresistive sensors ZMDI (Dresden, Germany) has added the ZSSC5101, an automotivequalified sensor signal conditioning IC for contactless position sensors based on magnetoresistive technology. The ZSSC5101 can directly interface with magnetoresistive sensor bridges such as AMR (anisotropic magnetoresistive), GMR (giant magnetoresistive) and TMR (tunnel magnetoresistive) sensors, enabling up to 360° angle sensors or high-resolution linear motion sensors. The chip automatically compensates for temperature drifts of the sensor, allowing superior accuracy over its full temperature range of -40°C to +150°C. 10W charger design meets latest specs Using its InnoSwitch ICs, this reference design from Power Integrations for a 10W CV/CC charger meets DOE-6 and European CoC Version 5, Tier 2 efficiency standards at the end of the cable. RDK-420 is a reference design kit for a 10W CV/CC USB charger based on PI’s InnoSwitch-CH family of highly integrated switcher ICs. InnoSwitch ICs combine the primary-side switch together with primary and secondary controllers and feedback circuits into a single, worldwide safety-rated, surface-mount package. Complete article, here Imagination tunes IP for low-power, integrated-wireless IoT connectivity ICs SoC designers of low-power connected devices can select a modular implementation of wireless LAN (Wi-Fi 802.11n), Bluetooth Smart, or both, on their chip, using Imagination Technology’s Ensigma Whisper Cores. The family of cores and peripherals has been shaped for lowest power consumption connectivity IP for wearables and IoT. Imagination designed the Ensigma Whisper flexible connectivity IP family (first release: September 2014) to enable the integration of ultra-low power communications in SoCs that will require extended battery life and low cost points. Complete article, here 200W, 98%, 10x14mm buck-boost regulators Vicor has added to its Picor Cool-Power ZVS Point of Load (PoL) Regulator portfolio with its high efficiency PI3749, PI3751, and PI3755 buck-boost regulators; the DC-DC buck-boost modules provide over 200W and over 98% peak efficiency. By minimising switching losses, Picor’s ZVS (zero-voltage switching) topology maintains a high efficiency over the specified Vin range; high frequency operation (up to 2.5 MHz) enables highest power density and fastest transient response. The LGA System in Package (SiP) has integrated controller, power switches and support components. Complete article, here Complete article, here 39 EDN Europe | MAY 2015 www.edn-europe.com
