DC/DC controller with wide duty cycle range
Texas Instruments' LM25145 42V synchronous buck controller is designed to regulate from a high input voltage source or from an input rail subject to high voltage transients, minimising the need for external surge suppression components. A high-side switch minimum on-time of 40ns facilitates large step-down ratios, enabling the direct step-down conversion from a 24V nominal input to low-voltage rails for reduced system complexity and solution cost...
I2C controlled 6A three-level switch mode single-cell charger
Texas Instruments' BQ25910 is an integrated three-level switch-mode parallel battery charge management device for single cell Li-ion and Li-polymer batteries. Utilisation of the three-level converter maintains highest switch-mode operation efficiency while reducing solution footprint and increasing power density. The device supports fast charging with high input voltage for a wide range of portable devices.
Added functionality to SimSurfing design support software
Murata has added extra functionality to their popular on-line ‘SimSurfing’ tool for simulation of the company’s capacitor, inductor and filter components. The previous version of the tool allowed visualisation of individual component performance characteristics for impedance, transmission and reflection variation, with frequency and other operating conditions.
Expanded portfolio of ULTEM UTF120 film for dielectric capacitors
At PCIM (Power Conversion and Intelligent Motion) Europe 2018, SABIC introduced two new gauges of ULTEM UTF120 polyetherimide (PEI) dielectric film for high temperature, professional-grade capacitor applications.
