OKY-T/3,T/5-D12 Series www.murata-ps.com Adjustable Output 3 and 5-Amp DOSA-SMT DC/DC Converters PRODUCT OVERVIEW The OKY-T/3 and -T/5 series are miniature frequency synchronous buck converter switching non-isolated Point-of-Load (POL) DC/DC power topology, the high power conversion ef cient Point converters for embedded applications. The module of Load (POL) module features programmable is fully compatible with Distributed-power Open output voltage and On/Off control. These converters Standards Alliance (DOSA) industry-standard also include under voltage lock out (UVLO), output speci cations (www.dosapower.com). Applications short circuit protection, over-current and over include powering CPUs, datacom/telecom systems, temperature protections. programmable logic and mixed voltage systems. These units are designed to meet all standard The wide input range is 8.3 to 14 Volts DC. Two UL/EN/IEC 60950-1 safety and FCC EMI/RFI Typical unit maximum output currents are offered, 3 Amps (T/3 emissions certi cations and RoHS-6 hazardous models) or 5 Amps (T/5 models). Based on xed- substance compliance.

Vin must be 2V or higher than Vout for 3.3 to 5V outputs. These are partial model numbers. Please refer to the part number structure for complete ordering part numbers. Ripple and Noise is shown at Vout=1V. See specs for details. All specifications are at nominal line voltage, Vout=nominal (5V for D12 models) and full load, +25 C. unless Max. VOUT = 5.1V at IOUT = 5A. otherwise noted. Max. VOUT = 5.1V at IOUT = 3A. Output capacitors are 1 F ceramic and 10 F electrolytic in parallel. Input cap is 22 F. See detailed specifica- tions. I/O caps are necessary for our test equipment and may not be needed for your application.
