Lisbon, Portugal—Chipidea has developed a step-down DC/DC converter IP core to support an external supply voltage up to 4.2V while using regular 3.3V SoCs found in low-cost CMOS processes.
The CI2512tl step-down DC/DC converter IP core allows SoC designers to integrate DC-DC converter functionality into their designs and avoid the additional expense of higher voltage process options.
The CI2512tl step-down DC/DC converter IP core maintains a high efficiency power conversion of greater than 90 percent over a large load range (up to 150mA) using PWM / PFM (Pulse Width Modulation/Pulse Frequency Modulation) controls. It accepts any battery with a voltage supply ranging from 2.7V to 4.2V, such as a lithium battery, and features a programmable output voltage ranging from 0.6V to 2.0V.
The IP core comes with a fully functional Verilog behavior model to ease integration and system verification.
