Typical unit
PRODUCT OVERVIEW
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 8.3 to 14 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 and FCC EMI/RFI emissions certifications and RoHS-6 hazardous substance compliance.

➀ The input voltage range must be 13.2 Volts max. for Vout >= 3.63 V.
② All specifications are at nominal line voltage, Vout=nominal (5V for D12 models) and full load, +25 deg.C. unless otherwise noted. Output capacitors are 1 μF ceramic and 10 μF electrolytic in parallel. Input cap is 22 μF. See detailed specifications. I/O caps are necessary for our test equipment and may not be needed for your application.
③ Use adequate ground plane and copper thickness adjacent to the converter. ④ Ripple and Noise (R/N) is shown at Vout=1V. See specs for details.
