Okami’s OKL family of non-isolated point-of-load (PoL) DC/DC converters from Murata Power Solutions feature the inspectable Land Grid Array (iLGA) package. The iLGA package, utilised on the new OKL-T/3-W12 series, features small plated cutouts (castellations) that allow probing and visual inspection of all signal pads. Its large copper pads provide a very low thermal impedance path between the module and the board onto which it is mounted.
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 12V (4.5V to 14V) input and a maximum output current of 3A. It uses the latest industry accepted standard pad layout for interconnects. The company says a combination of extremely high power density and a small footprint of just 12.2 by 12.2 mm makes the new modules especially useful in designs where board space is limited. It has a programmable output voltage range of 0.591V to 5.5V which is user-selected via an external resistor. They also feature 600kHz switching frequency, which offers the potential for improved transient response with reduction of output capacitance.
