PRODUCT OVERVIEW
OKX T/10 & T/16-W5 Series
Adjustable DOSA 10/16-Amp SIP DC/DC Converters
Typical unit
The OKX-T/10 and -T/16 series are miniature SIP 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 2.4 to 5.5 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 programmable output voltage and On/Off control. An optional Sequence/Tracking input allows controlled ramp-up and ramp-down outputs. The Sense input provides load compensation. 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 RoHS6 hazardous substance compliance.

The input voltage range must be 0.5V greater than the output voltage. All specifications are at nominal line voltage, Vout=nominal (3.3V for W5 models) and full load, +25 deg.C. unless otherwise noted. Output capacitors are 1 F ceramic and 10 F electrolytic in parallel. Input cap is 22 F. See detailed specifications. I/O caps are necessary for our test equipment and may not be needed for your application.
Use adequate ground plane and copper thickness adjacent to the converter. Ripple and Noise (R/N) is shown at Vout=1V. See specs for details.
