60V Buck-Boost Controller Drives High Power LEDs Download White Paper 78Ko

The LT®3791 is a 4-switch synchronous buck-boost DC/DC converter that regulates both constant-current and constant-voltage at up to 98.5% efficiency with a single inductor. It can deliver hundreds of watts and features a 60V input and output rating, making it ideal for driving high power LED strings and charging high voltage batteries when both step-up and step-down conversion is needed.

This month, Oscium is giving away three of its iMSO-204L dual analogue iOS oscilloscopes, worth USD400 each. Designed with native Lightning compatibility, the iMSO-204L transforms the iPad, iPhone, and iPod touch into an ultra-portable, two-channel oscilloscope.

Since Apple changed its connector, Oscium has been working to bring native compatibility to its customers. The third generation of handheld engineering tools from Oscium, the iMSO-204L is the solution to the connector change, featuring two analogue and four digital channels, capable of 50 MSPS at a 5MHz bandwidth, and with a resolution varying from 200ns/div to 10s/div.
