OKL-T/3-W12 Series www.murata-ps.com Programmable Output 3-Amp iLGA SMT PoLs PRODUCT OVERVIEW The OKL-T/3 series are miniature non-isolated Point-of-Load (PoL) DC/DC power converters for embedded applications. Featuring iLGA inspectable Land Grid Array (LGA) format, the OKL measures only 0.48 x 0.48 x 0.25 inches (12.2 x 12.2 x 6.35 mm). The wide input range is 4.5 to 14 Volts DC. The maximum output current is 3 Amps (T/3 models). Based on fixed-frequency synchronous buck converter switching topology, the high power conver- Typical unit sion efficient Point of Load (PoL) module features programmable output voltage and On/Off control. These converters also include under voltage lock out (UVLO), output short circuit protection, overcurrent and over temperature protections. An optional sequence/tracking feature on OKL2 models allows power sequencing of PoL’s. These units are designed to meet all standard UL/EN/IEC 60950-1 safety certifications and RoHS-6 hazardous substance compliance. FEATURES ■ iLGA inspectable Land Grid Array ■ 4.5-14Vdc input voltage range ■ Programmable output voltage from 0.591-5.5Vdc ■ Drives up to 200 μF ceramic capacitive loads ■ High power conversion efficiency at 93% ■ Outstanding thermal derating performance ■ Over temperature and over current protection ■ On/Off control and Power Good signal ■ Optional Sequence/Tracking operation (OKL2 models) ■ Designed to meet UL/EN/IEC 60950-1 safety (pending) ■ RoHS-6 hazardous substance compliance Contents of full data sheet Description, Connection Diagram, Photograph Ordering Guide, Model Numbering, Product Label Mechanical Specifications, Input/Output Pinout Detailed Electrical Specifications Output Voltage Adjustment, Application Notes Soldering Guidelines Performance Data and Oscillograms Tape and Reel Information Page 1 2 3 4 5 7 8 15 Connection Diagram +Vin F1 On/Off Control +Vout t4XJUDIJOH Controller Sense t'JMUFST t$VSSFOU4FOTF External DC Power Source Trim Open = On Closed = Off (Positive On/Off) Reference and Error Amplifier Common Sequence/Tracking (OKL2 Models) Common Power Good out Figure 1.

See detailed specs. All specifications are at nominal line voltage, Vout=nominal (5V for W12 models) and full load, +25 deg.C. unless otherwise noted. ➂ Use adequate ground plane and copper thickness adjacent to the converter. fRipple and Noise (R/N) and no-load input current are shown at Vout=1V. See specs for details. Output capacitors are 10 μF ceramic. Input cap is 22 μF. See detailed specifications. I/O caps are necessary for our test equipment and may not be needed for your application.
