HV9150DB1
Hysteretic DC/DC Controller Demoboard
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 configured 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.
Board Layout
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.

HV9150DB1
LDO (Linear Regulator) and CP (Charge Pump) Internal and External Voltage Reference Option
The HV9150 can be configured to use either an internal or
Mode Option
The HV9150 can operate in either LDO or CP modes. The
CP mode is preferred if the voltage of the input supply is
lower than 5V. The internal charge pump converter can
generate a higher voltage supply to drive the gate driver. If
a higher supply voltage is available, the LDO mode should
be chosen. The following table shows the options to select
between LDO and CP modes.
external voltage reference. The demoboard is set to use the
internal voltage reference. In order to use external voltage
reference, the user can replace the RREF 0Ω jumper with
a 0.1µF decoupling capacitor and connect the external
reference to the TP5 terminal. Please be aware that the EN
pin is required to toggle once to activate the device to enable
the external voltage reference option.
The R10 and D3 form an independent 3.3V output startup
circuit to set the device to LDO mode operation. These
components are not required on the demoboard if the CP
mode operation is preferred.
Modification to 300V Output Operation
The demoboard can be reconfigured to generate a 300V
output voltage. The user can replace the MOSFET driver
with one rated at 300V and adjust the value of potentiometer
to obtain a 300V output voltage. Since the ON-resistance
is different, the maximum output current may change. The
user can adjust the switching frequency or duty cycle to
compensate for the lower ON-resistance. Please see the
table below.
