Superpower = super regulation for high voltage

Superpower uses a floating current reference to provide regulation at any voltage, allowing the output voltage to be set with a single resistor. The entire reference circuit is bootstrap powered from the regulated output voltage for best performance.

Superpower High Voltage PCB

The following oscillograms demonstrate line and load regulation.

Line regulation—65mV sawtooth ripple on 300V DC(bottom), AC output (top)

High Voltage Line Regulation - 120Hz rejection

A 300V DC input signal contains typical full wave rectified ripple as a sawtooth wave. The above signal has ripple of 65mVpp, which is cleanly removed by a Superpower.

Load regulation—33mA through 10K (bottom), output voltage (top)

Line regulation, 300mA load
This illustrates again the low output impedance and clean, fast dynamic response of a Superpower. The lower trace is a 300V change across a 10K ohm load, for 30mA pulsed load current (10W). The top trace shows a mere 10mV change in Vout.

New 1.2V Superpower!

Announcing our latest breakthrough! A Superpower designed for the new lower voltage circuits such as those using the ESS Sabre DAC. This includes products from Oppo, Peachtree audio, twistedpear Buffalo DAC and more. SPLV is a variation on our patent pending design to allow the internal circuit to work even when powered by the very low Vout. The data sheet will be completed soon and parts are available to order NOW on our order page.

Transformer Calculator!

We have a new Transformer Calculator to calculate the minimum Vrms voltage of a transformer for your Superpower based supplies.
