OKL-T/3-W12 Series www.murata-ps.com Programmable Output 3-Amp iLGA SMT PoLs Typical unit FEATURES PRODUCT OVERVIEW The OKL-T/3-W12 series are miniature ef cient Point of Load (PoL) module features iLGA inspectable Land Grid Array non -isolated Point-of-Load (PoL) DC/DC power programmable output voltage and On/Off control. 4.5-14Vdc input voltage range converters for embedded applications. Featuring These converters also include under voltage lock Programmable output voltage from 0.591-5.5Vdc inspectable Land Grid Array (iLGA) format, the out (UVLO), output short circuit protection, and OKL-T/3-W12 measures only 0.48 x 0.48 x 0.244 over-current protections. Drives up to 200 F ceramic capacitive loads inches max. (12.2 x 12.2 x 6.2 mm max.). An optional sequence/tracking feature on High power conversion ef ciency at 93% The wide input range is 4.5 to 14 Volts DC. OKL2-T/3-W12 models allows power sequencing of Outstanding thermal derating performance The maximum output current is 3 Amps. Based PoLs. These units are certi ed to all standard UL/EN/ on xed-frequency synchronous buck converter IEC 60950-1 safety certi cations (2nd Edition) and Short circuit and over current protection switching topology, the high power conversion RoHS-6 hazardous substance compliance.

The output range is limited by Vin. See detailed specs. Use adequate ground plane and copper thickness adjacent to the converter. All speci cations are at nominal line voltage, Vout=nominal (5V for W12 models) and full load, +25 deg.C. unless otherwise noted. Ripple and Noise (R/N) and no-load input current are shown at Vout=1V. See specs for details. Output capacitors are 10 F ceramic. Input cap is 22 F. See detailed speci cations.
