PRODUCT OVERVIEW
The OKL-T/6-W5 series are non-isolated
Point-of-Load (PoL) DC/DC power converters for
embedded applications. Featuring inspectable Land
Grid Array (LGA) format, the OKL-T/6-W5 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 2.4 to 5.5 Volts DC.
The maximum output current is 6 Amps. Based
on fixed-frequency synchronous buck converter
switching topology, the high power conversion
OKL-T/6-W5 Series
Programmable Output 6-Amp
iLGA
SMT PoLs
Typical unit
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, over-
current and over temperature protections.
An optional sequence/tracking feature 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.
