Adjustable Output 3 and 5-Amp DOSA-SMT PoLs
PRODUCT OVERVIEW
The OKY-T/3 and -T/5 series are miniature 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
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
include powering CPU’s, datacom/telecom systems, temperature protections.
distributed bus architectures (DBA), programmable
logic and mixed voltage systems.
The wide input range is 2.4 to 5.5 Volts DC. Two
maximum output currents are offered, 3 Amps (T/3
models) or 5 Amps (T/5 models). Based on fixed-
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.
