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 Ambiq Micro is giving away five of its 'Apollo EVB' evaluation boards, worth 9 each for EETimes Europe’s readers to assess the capabilities of their cutting-edge Apollo sub-threshold microcontroller.

The new suite of Apollo MCUs is based on the 32-bit ARM Cortex-M4 floating point microcontroller and redefines 'low power' with energy consumption that is typically five to ten times lower than that of MCUs of comparable performance (thanks to Ambiq’s patented Subthreshold Power Optimized Technology platform).
