This is a look back of Allegro’s A6267 released since 2012. The A6267 is a high current DC-DC converter that drives high power LEDs in series designed for automotive application. Driving the LEDs in ...

Modern power delivery systems with DSPs, FPGAs and CPUs run on lower supply voltages and consume higher current. In fact, sub-1 V voltages are everywhere now. Meanwhile, intermediate bus voltages have ...

Unveiled as the market's first single-chip, interleaved PWM controllers for 50A to 100A power supplies, the UCC28220 and UCC2821 peak current mode controllers are available in interleaved-forward or ...

Interesting question. Before we could really answer it, we had to read up on pulse width modulation and why virtually all of the OEs now use PWM to control their fuel systems. To be clear, we will ...

Linear Technology’s LTC3805 is a current-mode, programmable frequency PWM controller designed to reduce the size and complexity of flyback power supplies. The device features low start-up current, ...
