The OKY-T/10 and -T/16 series are miniature
SMT non-isolated Point-of-Load (POL) 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,
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 pro-
grammable output voltage and On/Off control. An
optional Sequence/Tracking input allows controlled
ramp-up and ramp-down outputs. The Sense input
provides remote sense. 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 RoHS-6 hazardous
substance compliance.
