Fast charging and system back up

Linear's LTC3110 is a 2A bidirectional buck-boost DC/DC regulator with capacitor charger and balancer. Its 0.1V to 5.5V capacitor/battery voltage and 1.8 to 5.25V system backup voltage ranges suit it to a variety of backup applications using supercapacitors or batteries, including servers, RAID systems and RF systems.

Resettable e-fuse for consumer applications

Diodes Inc has introduced the NIS5135, a self-protected resettable electronic fuse designed to enhance system reliability against shutdown and catastrophic failures. The fuse is suited to plug and play consumer applications, such as hard disk and solid state drives, printers, and set-top boxes.

MOSFETs enhance buck converter power density

Diodes has introduced the DMC1028UFDB complementary MOSFET pair. Aimed at increasing the power density of DC/DC converters, the MOSFET pair integrates an N-channel and a P-channel MOSFET in a DFN2020 package. The design is customised for point-of-load converters that step down from 3.3V to 1V for core voltage supply to ASICs.

Industry's smallest 20A power module

Exar has introduced the XR79120, a 20A single output, synchronous step-down power module in a 12 x 14 x 4mm package. The XR79120 is claimed to offer greater than 93% peak efficiency and leverages constant on-time (COT) control architecture across a 4.5 to 22 VIN range. This allows single supply operation from industry standard 5, 12 and 19.6V rails.

Converters offer wide input range in a compact package

XP Power has launched the ITQ series of 6W DC/DC converters. Packaged in a compact SIP 8-pin format, with a footprint of 21.9 x 11.1 x 9.2mm, the ITQ series takes up less board space giving designers more room to add features or the ability to reduce end product size.

High efficiency in hard switching applications

Infineon has extended its medium voltage MOSFET portfolio with Optimise 300 V, which is said to enable energy efficient solutions in applications such as telecom systems, uninterruptible power supplies (UPS), motor control, industrial power supplies and DC/AC inverters.

Buck converter raises portable efficiency

Diodes claims that its AP3403 step-down DC/DC converter achieves typical efficiencies greater than 95%, helping to extend the battery life of low voltage portable products. The synchronous PWM device drives a load of up to 600mA, with efficiency maintained through a configuration of external resistor, capacitor and inductor components.

Efficient PMIC halves input voltage

Dialog has released the DA9312, a power management IC suitable for applications supplied directly from dual cell (2S) stacked lithium battery packs or from input voltages range from 5.5 to 10.5V. It integrates three independent power supplies: two DC/DC buck regulators, each delivering up to 5A; and what is said to be the industry's first inductorless 10A power converter.

Power converters for white goods

Dialog Semiconductor has announced the iW1818 and iW1830 AccuSwitch pulse width modulation (PWM) controllers. These power control circuits use Dialog's PrimAccurate primary-side control to eliminate the need for optocouplers in white goods, said to be the weakest link in achieving high reliability and long operating lifetime for appliances, such as dishwashers, refrigerators, cooking ranges and microwaves.

Ultra-low power SRAM IP

SureCore's latest ultra-low power SRAM IP technology is said to extend battery life and reduce both static and dynamic power through its patented suite of circuit design techniques. This is crucial for developers of wearable electronics and IoT applications.

Buck controller eliminates intermediate power conversion

The ISL8117, from Intersil, is a 60V synchronous step-down PWM buck controller that can bypass the intermediate step-down conversion stage traditionally employed in industrial applications. Its low duty cycle (40ns minimum on time) enables the direct step-down conversion from 48V to a 1V point-of-load. This makes it possible for designers to reduce system complexity and solution cost in industrial, factory automation, medical and communications infrastructure applications.

HV-IPD for sine-wave motor control

Toshiba has launched the TPD4204F, a high voltage intelligent power device that enables the sine-wave control of brushless DC electric motors. The device can be used in a range of low power industrial fans and pumps, as well as in white goods such as washing machines, dishwashers and fan units.

Power management chipset helps optimise dead time

Texas Instruments has introduced a power management chipset with intelligent digital control and a body-diode sensing feature to optimise secondary-side synchronous rectification in next-generation AC/DC and isolated DC/DC power supplies.

Wide input and noise immunity DC/DC converters

The DDC15 and DDC30 series of low profile 15W and 30W DIN rail format DC-DC converters have been announced by XP Power. The single output converters accept inputs in the range from 9 to 36V DC, suiting a 12 or 24V DC nominal input. The range is designed to offer additional voltages in DIN rail power systems, provide isolated outputs and noise immunity or support battery powered or battery backed applications.
