The latest addition to the Okami family of non-isolated point-of-load (PoL) DC-DC converters features a 12.2-mm x 12.2-mm inspectable land grid array (iLGA) package. Unlike conventional LGA configurations , the iLGA package features small-plated cutouts (castellations) that allow probing and visual inspection of all signal pads. It also exhibits excellent heat-management characteristics because the large copper pads provide a very low thermal impedance path between the module and the board. The OKL-T/3-W12 series comprises two models to give designers a choice of either positive or negative on/off logic. The compact modules have a nominal 12-V (4.5 V to 14 V) input and a maximum output current of 3 A. The programmable output voltage that ranges from 0.591 V to 5.5 V is user-selected via an external resistor. These new modules are able to drive ceramic capacitive loads up to 200 µF, and overall efficiency is up to 93%. They also feature 600-kHz switching frequency, which offers the potential for improved transient response with reduction of output capacitance. The OKL-T/3-W12 series is RoHS-compliant and designed to meet UL/EN/IEC 60950-1 safety approvals and FCC emissions certifications. Operating temperature range is ?40°C to +85°C. The OKL-T/3 model costs in the low $3 range in large quantities. Lead time is from six to eight weeks. MURATA POWER SOLUTIONS INC., Mansfield, MA. (508) 339-3000.
