Step-Down DC/DC Converter Core from Chipidea®
Campbell, CA — Chipidea® has introduced what it calls the industry's most compact, silicon-proven step-down DC/DC converter IP core of its type. It is designed to support an external supply voltage up to 4.2V while using regular 3.3V System-on-Chip (SoC) devices 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. It reportedly 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. The converter accepts any battery with a voltage supply ranging from 2.7 to 4.2V, such as a lithium battery, and has a programmable output voltage ranging from 0.6V to 2.0V.

The high programmability of the DC/DC IP core output voltage gives SoC integrators full flexibility to optimize system performance. The IP core achieves a high level of integration including internal references, internal regulators and system power-on-reset to enable a "plug-and-play" power management functionality. The IP core comes with a fully functional Verilog behavior model to ease integration and system verification.
