PRODUCT OVERVIEW
isolated Point-of-Load (POL) DC/DC power convert-
ers for embedded applications. The module is fully
compatible with Distributed-power Open Standards
Alliance (DOSA) industry-standard specifi cations
(www.dosapower.com). Applications include pow-
ering CPU’s, datacom/telecom systems, program-
mable logic and mixed voltage systems.
maximum output currents are offered, 10 Amps
(T/10 models) or 16 Amps (T/16 models). Based
on fi xed-frequency synchronous buck converter
switching topology, the high power conversion
The OKY-T/10 and -T/16 series are SMT non-
The wide input range is 2.4 to 5.5 Volts DC. Two

effi cient 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.
UL/EN/IEC 60950-1 safety and FCC EMI/RFI
emissions certifi cations and RoHS-6 hazardous
substance compliance.
