DC/DC Converter Offers Small Footprint, Integrated Inductor
Enpirion announced the availability of its 1500 mA (1.5 A) synchronous buck DC/DC converter with an integrated inductor. The EP53F8QI offers a small footprint and high efficiency. This switch-mode converter delivers up to 1,500 mA of continuous output current and up to 5.5 W of output power. The device is housed in a 3 mm x 3 mm x 1.1 mm QFN package, including the integrated inductor. With a total solution size of just 40 mm², the EP53F8QI has a power density of 140 mW per mm². The part also achieves up to 94 percent efficiency, making it appropriate for USB wireless datacards, where efficiency is required to meet the USB power specification, while maintaining small footprint. Built on the company's high frequency CMOS and magnetics, the EP53F8QI integrates the control and protection circuitry with gate drive, power MOSFETS, compensation network and the power inductor. The 4 MHz switching frequency and integrated inductor ensure low output ripple and low conducted and radiated noise. Output voltage is programmed through an external divider, providing maximum design flexibility. The ENP53F8QI is available now, and pricing is set at $1.36 for quantities of 10,000 parts.
