OKY-T/10 & T/16-W5 Series www.murata-ps.com Programmable DOSA-SMT 10/16-Amp DC/DC Converters PRODUCT OVERVIEW Typical unit FEATURES The OKY-T/10 and -T/16 series are SMT nonisolated 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 Wide 2.4-5.5 VDC input range Non-isolated output adjustable from 0.7525 to 3.63 Volts up to 16 Amps DOSA-compatible SMT package 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 remote sense. 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.
