PRODUCT OVERVIEW
The OKL-T/3 series are miniature non-isolated
Point-of-Load (PoL) DC/DC power converters for
embedded applications. Featuring
iLGA
inspectable
Land Grid Array (LGA) format, the OKL measures
only 0.48 x 0.48 x 0.25 inches (12.2 x 12.2 x 6.35
mm).
The wide input range is 4.5 to 14 Volts DC. The
maximum output current is 3 Amps (T/3 models).
Based on fixed-frequency synchronous buck con-
verter switching topology, the high power conver-
OKL-T/3-W12 Series
Programmable Output 3-Amp
iLGA
SMT PoLs
Typical unit
sion 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 on OKL2
models allows power sequencing of PoL’s. These
units are designed to meet all standard UL/EN/IEC
60950-1 safety certifications and RoHS-6 hazard-
ous substance compliance.
