The EN2300 family of integrated 12-V dc/dc converters are implemented in a power MOSFET technology featuring double the power density compared to alternative solutions. The devices have solution footprints from 4-A at 190 mm2 to 15-A at 308 mm2 which represents up to a 60% area reduction versus competing alternatives at comparable performance. The devices support an input voltage range of 4.5 to 14 V and an output voltage range of 0.6 to 5 .The devices integrate a controller, power MOSFETs, high-frequency input capacitors, a compensation network and an inductor. They target telecommunication, enterprise, industrial, embedded computing, and storage systems applications.
The additions to the family of converter include the 4A EN2340QI, 6A EN2360QI, 9A EN2390QI, and 15A EN23F0QI devices. The EN2300 family uses a proprietary high-speed transistor structure implemented in 0.18 µm LDMOS process to achieve the industry’s best Figure of Merit of 20 (FOM = gate charge x on-state resistance in units of mΩ nC) to operate at high frequency while reducing switching losses. (Ea/1,000: 4-A EN2340QI, $3.56; 6-A EN2360QI, $4.41; 9-A EN2390QI, $6.60; 15-A EN23F0QI, $9.00 available now.)
