PRODUCT OVERVIEW
The OKX-T/3-D12 series are miniature SIP non-
isolated Point-of-Load (POL) DC/DC power convert-
ers for embedded applications. The module is fully
compatible with Distributed-power Open Standards
Alliance industry-standard specifications.
Applications include powering CPU’s, datacom/
telecom systems, programmable logic and mixed
voltage systems. The wide input range is 8.3 to
13.8 Volts DC at 3 amps. 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. These converters also include under
voltage lock out (UVLO), output short circuit protec-
tion, over-current and over temperature protections.
These units are designed to meet all standard UL/
EN/IEC 60950-1 safety certifications and RoHS-6
hazardous substance compliance.
