PRODUCT OVERVIEW

isolated Point-of-Load (PoL) DC/DC power convert-

ers for embedded applications. The tiny form factor

is conﬁ gured on a Land Grid Array (LGA) assembly

measuring only 0.48 x 0.48 x 0.244 inches max.

(12.2 x 12.2 x 6.2 mm max.).

The maximum output current is 3 Amps. Based

on ﬁ xed-frequency synchronous buck converter

switching topology, the high power conversion

The OKL-T/3-W5 series are miniature non-

The wide input range is 2.4 to 5.5 Volts DC.
