For battery powered systems it can be useful to know something about the state of the battery in order to predict remaining battery life. With specific charge/discharge information, you could also manage battery consuming resources to maximize battery life. There are integrated circuits to help with either approach. For simple charge or discharge information, a […]

New power-backup source for data centers: Supercapacitors
Price points for supercapacitor technology are declining and the standards for backup times in data centers are dropping, says power systems manufacturer Inventus Power in Woodridge, Ill. So it makes sense for supercapacitors to become an alternative technology to Lithium-ion and lead acid batteries, the company says. Consequently, Inventus Power is has developed supercapacitor products […]
Low-noise buck-boost charge pump regulates from 2.7 to 38 V
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC3246, a compact, low noise buck-boost charge pump with integrated watchdog timer capable of up to 500mA of output current. The LTC3246 uses multimode switched capacitor conversion to maintain regulation over a wide 2.7V to 38V input voltage range and produces a regulated 3.3V, 5V, […]
Low-profile gate drive transformers feature 1.5 kV isolation
The new MID-GDT transformer series is now available from Wurth Electronics Midcom. These low profile gate drive transformers are surface mount with a maximum height of 5.38mm, and operate with a voltage-time product of at least 70 Vµs on secondary windings. These pick-and-placeable transformers feature 1500V isolation, and have an operating temperature of -40° to […]

BLDC gate drivers, power MOSFETs take up little PCB space
Today Texas Instruments (TI) introduced two new device families that help reduce size and weight in motor drive applications. When used together, DRV832x brushless DC (BLDC) gate drivers and CSD88584/99 NexFET™ Power Blocks require as little as 511 mm2, half the board space of competing solutions. The DRV832x BLDC gate drivers feature a smart gate-drive architecture that […]
Controller handles USB-C power delivery spec
Fresco Logic live demonstrated the industry’s first USB-C™ Programmable Power Supply solution Compliant to Power Delivery(PD) 3.0 Rev 1.1 Specification at Taipei Computex 2017. The first demo showcased Fresco Logic’s Panther Creek-based FL7103 PD controller and a Partner’s buck-boost technology. Fresco Logic will provide a series PPS compliant charger solutions that will enable customers to fast […]
DC switch modules handle up to 15 A
DC current design and installations in enclosures and panels are on the rise. For example, in telecommunication applications, where stand-alone and uninterrupted power supply is a top priority. STEGO unifies the DC versions of its products under the name of DC Line and, with the DCM 010, places its versatile DC switch module in the […]
25 mΩ, 200V eGaN FET meets size and performance demands
EPC announces the EPC2046 power transistor for use in applications including wireless power, multi-level AC-DC power supplies, robotics, solar micro inverters, and low inductance motor drives. The EPC2046 has a voltage rating of 200 V and maximum RDS(on) of 25 mΩ with a 55 A pulsed output current. The chip-scale packaging of the EPC2046 handles […]
Electric double layer capacitors optimized for smart grids and meter infrastructure
Panasonic Automotive & Industrial Systems Europe announces the introduction of the LF Series in its stacked-coin type line-up of Electric Double Layer Capacitors (EDLCs). The LF Series offers low resistance, and minimal leakage current combined with a rated lifetime of 6,000 hours – the longest available in the market. With a 5.5V nominal rating, capacitance […]
