TDK adds to DC-DC converter series

image

TDK Corporation has added two models to the TDK-Lambda i6A series of step-down, non-isolated DC-DC converters. The i6A4W is capable of supplying currents of up to 20A, and the i6AN allows the creation of negative voltages delivering currents up to 8A. Both can be used in conjunction with the previously announced 14A rated i6A series to generate additional system voltages ...

TI adds to NexFET FemtoFET mosfets

image

TI has introduced a 60-V N-channel power FemtoFET power transistor in a 1.53×0.77mm silicon-based package with a typical on-resistance (Rdson) of 54m designed to replace standard small-signal mosfets in space-constrained industrial load-switch applications. The CSD18541F5 expands TI’s NexFET technology portfolio of FemtoFET mosfets to include higher voltages and manufacturing-friendly footprints. CSD18541F5 key features and benefits Ultra-low 54-mΩ of Rdson at ...

8W isolated DC-DC is smaller than a square inch

An 8W isolated DC-DC converter has been designed in to a 16-pin DIP package measuring only 0.94 x 0.54 x 0.31-inch. The MDW08 family from US-based supplier Minmax offers 9-18 / 18-36 / 36-75Vdc input ranges with single and dual output models ranging 3.3 – 15Vdc delivering 8W of output power an encapsulated package. All models feature: I/O Isolation of ...

Toshiba launches chip load switch ICs

6841A_LRES

Toshiba has launched three single-chip load switch ICs, the TCK106AF, TCK107AF and TCK108AF. Integrating high performance chips in an industry-standard SOT-25 package, Toshiba’s new ICs combine on-resistance ratings down to just 63mΩ and low typical quiescent currents of 110nA with low loss, low standby current and high performance switching characteristics. Fabricated using a Toshiba CMOS process that combines an output ...

Diamond to stock MagnaChip mosfets

Diamond Magnachip mosfets

Diamond Power Components is to distribute power mosfets from Korean chipmaker MagnaChip Semiconductor. “MagnaChip are a major player in the power mosfet market, supplying global OEMs with semiconductors for all segments of power control and LED Lighting applications,” said Diamond sales director Peter Hall. “Having complete control of their own design and manufacturing processes allows MagnaChip to adopt an aggressive cost ...

Battery fuel gauge chips include anti-clone security

MAX172xx

Maxim has introduced battery energy measuring (‘gas gauging’) chips with SHA-256 anti-cloning authentication. The firm has developed its own gauging algorithm that does needs no host interaction. “ModelGauge m5 fuel gauges include an algorithm that converts raw measurements such as battery voltage, current, and temperature into accurate state-of-charge, absolute capacity in mAhr, time-to-empty, and time-to-full while charging,” said the firm, ...

New topology gives TI 10MHz dc-dc conversion

TI TPS54A20 dc dc

Texas Instruments has unveiled a new dc-dc topology, and with it is claiming industry’s highest current density for a 12V, 10A, 10MHz dc-dc converter at 50A/cm3. Similar to a two-phase buck converter, the added series capacitor allows the switching transistors to operate at half the input voltage, more than halving switching losses, TI energy systems engineer Pradeep Shenoy told Electronics Weekly. ...

Rohm feeds NXP MCUs with multi-output power chip

Rohm BD71815GW

Rohm has announced a multi-function power chip (PMIC) for NXP’s i.MX 7Solo and i.MX 7Dual processors. Called BD71815GW, it has five low-quiescent current buck regulators, seven LDOs, a JEITA-compliant 1S charger, a fuel gauge with Coulomb Counter, an LED driver and a real-time clock (RTC), alongside extensive monitoring and protection circuits. All possible processor power modes are supported, said Rohm, ...

Power converter puts 25W in square inch space

GetFileAttachment-2

CUI has added two open frame isolated DC-DC converters – the PRD15 and PRD25 series – with outputs of 15W and 25W respectively in one square inch of board space. The modules measure 27.90 x 24.40 x 8.10mm. The PRD15 series features a 4:1 input voltage range of 9-36 or 18-75Vdc, while the PRD25 series provides a 2:1 input voltage ...
