Boost regulator offers 95% efficiency, 3MHz switching

Linear Technology has introduced the LTC3124, a dual phase, 3MHz synchronous boost DC/DC converter with output disconnect and inrush current limiting.

The device's dual phase operation is said to reduce peak inductor and capacitor ripple currents, minimising component size while delivering lower output ripple compared to equivalent single phase solutions. The 18V switch can deliver output voltages as high as 15V from an input voltage range of 1.8V at start up ...

Load switch safeguards USB ports

Diodes has announced a single channel load switch, which it says ensures complete protection from interconnects subject to the risk of surges and short circuits. Optimised for regular USB and other hot swap applications, the device is provided in a small form factor SOT25 package, offering a footprint of only 9mm2.

MCUs come with larger flash and RAM options

A new family of 32bit MCUs has been released by Microchip. Available in 256/64KB Flash/Ram configurations, the devices come with software and tools for designs in digital audio with Bluetooth, USB audio, graphics, touch sensing and general purpose embedded control.
