DC/DC converter rated at 1.5A
( 01 Jul 2009 )

Enpirion’s EP53F8QI synchronous buck DC/DC converter is rated at 1.5A and delivers up to 5.5W of output power. The device is housed in a 3x3x1.1mm QFN package and achieves up to 94 percent efficiency—making it the highest efficiency device of its size.

Built on Enpirion’s proprietary high frequency CMOS and magnetics, the EP53F8QI integrates the control and protection circuitry with gate drive, power MOSFETS, compensation network and a power inductor. The 4MHz switching frequency and integrated inductor ensure low output ripple and low conducted and radiated noise.
