PRODUCT OVERVIEW
The OKX-T/10 and -T/16 series are miniature SIP
non-isolated Point-of-Load (POL) switch mode DC/DC
power converters for embedded applications. The
module is fully compatible with Distributed-power
Open Standards Alliance (DOSA) industry-standard
specifications (www.dosapower.com). Applications
include powering CPU’s, datacom/telecom systems,
distributed bus architectures (DBA), programmable
logic and mixed voltage systems.
The wide input range is 8.3 to 14 Volts DC. Two
maximum output currents are offered, 10 Amps
(T/10 models) or 16 Amps (T/16 models). 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.
An optional Sequence/Track input allows controlled
ramp-up and ramp-down outputs. The Sense input
provides load compensation. These converters also
include under voltage lock out (UVLO), output short
circuit protection, over-current and over tempera-
ture protections.
These units are designed to meet all standard
UL/EN/IEC 60950-1 safety and FCC EMI/RFI
emissions certifications and RoHS6 hazardous
substance compliance.
