Building a Low Cost, High Efficiency 12 V to 1 V POL Converter Using EPC2111
The smallest, most cost effective and highest efficiency non-isolated 12 V to 1.0 V POL converter, suitable for high-performance computing, crypto currency and telecommunication applications, can be achieved by employing monolithic eGaN® IC half-bridges such as the EPC2111. The EPC9204 configured as a synchronous Buck converter yielded a power density of 1000 W/in³ and is capable of delivering 12 A.
Conclusions：Migrating a high frequency 12 V to 1 V POL converter design from Silicon MOSFETs to eGaN FETs is an obvious choice due to higher efficiency, and also offers reduction in both size and cost. Table 1 shows the bill of materials that yields a cost per watt of less than $0.20. The eGaN FET based 12 V to 1 V, 12 A load converter was demonstrated to yield a peak efficiency of 78% at 5 MHz with a power density of at least 1000 W/in³, all with a cost below $0.20 per watt.
