Linear Technology Corporation introduces the LTC2645, a quad-channel 12-bit/10-bit/8-bit PWM-to-voltage output digital-to-analog converter (DAC) with 10ppm/°C reference. Oct. 15, 2014 2 min read ...

Any boost-converter design will have a practical limit to how much it can step up a voltage from input to output. Pulse-width modulation (PWM) controllers have timing limits that restrict the minimum ...

Selecting a PWM controller has become less straight forward as leading edge DSPs, FPGAs and CPUs run on increasingly lower supply voltages and consume higher current. Sub 1V voltages are becoming ...
