PRODUCT OVERVIEW

lated Point-of-Load (PoL) DC/DC power converters

for embedded applications. Featuring inspectable

Land Grid Array (iLGA) format, the OKL-T/3-W12

measures 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-W12 series are miniature non-iso-

The wide input range is 4.5 to 14 Volts DC.
