The frequency I picked was arbitrary — about 333 kHz. Again, I just wanted a circuit you could experiment with and we’ll build the rest of the circuit around this core.

The circuit works according to a simple principle: a converter has always a mixer and an oscillator. The TBA120 can be used as the mixer. Its amplifier component can then be used as the oscillator by ...

As the number of Power Over Ethernet (PoE) powered device (PD) applications grows, market pressures are driving designers to lower the cost and complexity of the DC-DC converters that power them, ...
