Dual-sided cooling improves MOSFET heat dissipation

Dual-sided cooling improves MOSFET heat dissipation
Toshiba Electronics Europe has revealed that its high-efficiency, low-voltage MOSFETs are now available in ultra-compact DSOP Advance package options, which offer dual-sided cooling to improve heat dissipation by more than 30%. This enables designers to minimise the PCB temperature and improve performance without board space penalties in high-component-density applications.

Power system manager relieves computation & polling

Power system manager relieves computation & polling
Providing current, power and energy monitoring of the intermediate bus input to Point-of-Load (PoL) converters, a four-channel PMBus digital power system manager has been released by Linear Technology. By providing the energy consumed, reported in joules, and the elapsed time through a PMBus interface, the LTC2975 relieves computation and polling.

1A µDC/DC converter with integrated coil minimises radiated noise

1A µDC/DC converter with integrated coil minimises radiated noise
The XCL219/XCL220 module from Torex Semiconductor is designed to minimise unwanted radiated noise or EMI, making it suitable for sensitive RF applications. With its integrated coil, the XCL219/220 achieves a significant reduction in radiated noise across all frequency bands, when compared with a conventional DC/DC circuit with an external coil.

PFM-only DC/DC converter operates from just 0.5µA

PFM-only DC/DC converter operates from just 0.5µA
In A6.280 at electronica 2014, Torex Semiconductor will present the company's first PFM-only step-down DC/DC converter that has been specifically developed for ultra-low power applications. The XC9265 series consumes just 0.5µA during operation and is therefore suitable for applications that run from batteries for long periods of time.
