The OKR-T/10 series are SIP non-isolated Point-of-Load (PoL) DC/DC power converters measuring

only 0.41 x 0.65 x 0.3 inches (10.4 x 16.5 x 7.62 mm). The wide input range is 4.5 to 14 Volts DC. Based

on 600 KHz synchronous buck topology, the high power conversion efﬁ cient Point of Load (PoL) module

features programmable output voltage and On/Off control, under voltage lock out (UVLO), overcurrent and

over temperature protections. These units meet all standard UL/EN/ IEC 60950-1 safety certiﬁ cations and

RoHS-6 hazardous substance compliance.

OKR-T/10-W12 Series Adjustable Output 10-Amp SIP-mount DC/DC Converters Notes (1) All speciﬁcations are typical unless noted. General conditions for Speciﬁcations are +25 deg.C, Vin=nominal, Vout=nominal (no trim installed), full rated load. Adequate airﬂow must be supplied for extended testing under power. All models are tested and speciﬁed with external 1μF and 10 μF paralleled output capacitors and a 22 μF external input capacitor. All capacitors are low ESR types.

OKR-T/10-W12 Series Adjustable Output 10-Amp SIP-mount DC/DC Converters TECHNICAL NOTES Input Fusing Certain applications and/or safety agencies may require fuses at the inputs of power conversion components. Fuses should also be used when there is the possibility of sustained input voltage reversal which is not current-limited. For greatest safely, we recommend a fast blow fuse installed in the ungrounded input supply line. The installer must observe all relevant safety standards and regulations.

OKR-T/10-W12 Series Adjustable Output 10-Amp SIP-mount DC/DC Converters CAUTION: If you routinely or accidentally exceed these Derating guidelines, the converter may have an unplanned Over Temperature shut down. Also, these graphs are all collected at slightly above Sea Level altitude. Be sure to reduce the derating for higher density altitude.
