Introduction

The Supertex HV9606DB1 evaluation board demonstrates the features of HV9606 IC by presenting a DC/DC converter employing flyback technique to achieve multiple outputs:

• 3.3V non-isolated output with ± 1 accuracy. The output power is 350mW.

• 5V isolated output with ± 5 accuracy. The output power is 150mW.

• 40V nominal isolated output. The output power is 500mW.

The HV9606 current-mode PWM controller features a built-in start-up regulator that can be used to operate the IC from inputs of 15V to 250V. Other features include built-in soft start, programmable input under voltage lockout and hysteresis, and standby current of 6µA (below UVLO).
