PRODUCT OVERVIEW
The OKL-T/3-W12 series are miniature
non-isolated 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 wide input range is 4.5 to 14 Volts DC.
The maximum output current is 3 Amps. Based
on fixed-frequency synchronous buck converter
switching topology, the high power conversion
efficient Point of Load (PoL) module features
programmable output voltage and On/Off control.
These converters also include under voltage lock
out (UVLO), output short circuit protection, and
over-current protections.
An optional sequence/tracking feature on
OKL2-T/3-W12 models allows power sequencing of
PoL’s. These units are certified to all standard UL/EN/
IEC 60950-1 safety certifications (2nd Edition) and
RoHS-6 hazardous substance compliance.
