General Description

The Supertex HV9150DB1 demoboard is for the evaluation

of the HV9150 hysteretic DC/DC controller. This demoboard

consists of all necessary components to create a 5V to 200V

step up converter capable of providing 600mW of output

power.

This DC/DC converter has a single voltage input and a single

voltage output. The demoboard is congured to use the internal

voltage reference. In addition, the user also has access to an

external voltage reference pin if it is preferred. The output voltage

can be adjusted from 50V to 200V by adjusting the potentiometer

next to the output terminals.

The potentiometer is used in the resistor feedback network for

demonstration purposes.

The demoboard shows that all necessary components for this

600mW converter can be packed into a square inch, single sided,

PCB area.

To ensure a stable operation of the DC/DC converter, it is

recommended that a low ESR bulk decoupling capacitor be connect

at the input voltage supply.
