High Voltage IPs

High Voltage CMOS Design capabilities are not enough to bring a product to a reliable and effective production. You need not only a deep HV process knowledge, ESD and layout competences, but also power dissipation and packaging skills, physical interface, proven management capabilities, a high-level design experience and much more. Canova Tech can offer what is needed to turn an High Voltage concept into an excellent ASIC/IP product. With a proven record of successful designs, Canova Tech can offer solutions with High Voltage CMOS technologies (up to 120 with bulk/SOI substrates) for power management, motor driving, HV interfaces and more. Here Below some examples of silicon proven IPs on the HV domain that can speed up the Time To Market for our customers.

Targeting high voltage applications, CTBU2011 is a pwm synchronous buck dcdc converter with integrated high side and low side switches that can be used to provide a fixed 5V output voltage at 500mA of maximum load current from a up to 120V supply voltage. An external inductor and a capacitor are needed to implement the output filter while a diode and and capacitor are needed to generate the proper boot voltage for the switches driver. An external reference voltage (bandgap voltage) is necessary for correct operations: the target voltage is 1.2V. Integrated current sensing is used to sense and limit the dcdc converter supply current.
