Typical unit
OKL-T/6-W12 Series
Programmable Output 6-Amp iLGA SMT PoLs
PRODUCT OVERVIEW
The OKL-T/6-W12 series are miniature non-iso-
lated Point-of-Load (PoL) DC/DC power converters
for embedded applications. Featuring inspectable
Land Grid Array (iLGA) format, the OKL-T/6-W12
measures only 0.48 x 0.48 x 0.283 inches max.
(12.2 x 12.2 x 7.2 mm max.).
The wide input range is 4.5 to 14 Volts DC.
The maximum output current is 6 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/6-W12 models allows power sequencing
of PoL’s. These units meet all standard UL/EN/IEC
60950-1 safety certifications (2nd Edition) and RoHS-6
hazardous substance compliance.
