This versatile power converter controller provides dual outputs at a fixed switching frequency and can regulate either output voltage or target system delay (using an external -filter). In the voltage regulation mode, the output voltage is monitored with an analog-digital (A/D) converter, and the feedback compensation network is implemented digitally. The generation of the pulsewidth modulation (PWM) signal is done with a hybrid delay line/counter approach, which saves power and area relative

The key features of this design are its low-power dissipation, reconfigurability, use of either delay or voltage feedback, and multiple outputs. Index Terms-Dc/dc conversion, low power.
