OKR-T/10-W12 Series
Adjustable Output 10-Amp SIP-mount DC/DC Converters
PRODUCT OVERVIEW
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 efficient 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 certifications and
RoHS-6 hazardous substance compliance.
