OKR-T/3 Series
Adjustable Output 3-Amp SIP-mount DC/DC Converters
PRODUCT OVERVIEW
The OKR-T/3 series are miniature SIP non-isolated Point-of-Load (PoL) DC/DC power converters
measuring only 0.41 x 0.65 x 0.22 inches (10.4 x 16.5 x 5.6 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.
