PRODUCT OVERVIEW
The OKX-T/3-W5 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 2.4 to 5.5
Volts DC at 3 amps. Based on fixed-frequency syn-
chronous 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 temperature
protections. These units are designed to meet all
standard UL/EN/IEC 60950-1 safety certifications
and RoHS-6 hazardous substance compliance.
