Typical unit
OKL-T/3-W5 Series
Programmable Output 3-Amp iLGA SMT PoLs
PRODUCT OVERVIEW
The OKL-T/3-W5 series are miniature non-iso-
lated Point-of-Load (PoL) DC/DC power converters
for embedded applications. The tiny form factor is
configured on a Land Grid Array (LGA) assembly
measuring 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 2.4 to 5.5 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, 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.
