Programmable Output 1-Amp iLGA SMT PoLs
PRODUCT OVERVIEW
The OKL-T/1-W12 series are non-isolated Point- of Load (PoL) module features programmable
of-Load (PoL) DC/DC power converters for embed-
ded applications. Featuring inspectable Land Grid
Array (iLGA) format, the OKL-T/1-W12 measures
output voltage and On/Off control. These converters
also include under voltage lock out (UVLO), output
short circuit protection, and over-current protec-
only 0.488 x 0.488 x 0.18 inches max. (12.4 x 12.4 tions.
x 4.57 mm max.).
The wide input range is 2.9 to 14 Volts DC. The
These units are designed to meet all standard UL/
EN/IEC 60950-1 safety certifications (2nd Edition) and
maximum output current is 1 Amp. Based on fixed- RoHS-6 hazardous substance compliance.
