The latest addition to the Okami family of non-isolated point-of-load DC/DC converters from Murata, the OKL range, features the inspectable land grid array package.
The iLGA package, used on the OKL-T/3-W12 series, features small plated cutouts (castellations) that allow probing and visual inspection of all signal pads that is not possible with conventional LGA configurations. The package enables good heat management as the large copper pads provide a low thermal impedance path between the module and the board on which it is mounted.
The series consists of 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 to 14 V)input and a maximum output current of 3 A.
The series has a programmable output voltage range of 0.591 to 5.5 which is user-selected via an external resistor. These new modules can drive ceramic capacitive loads up to 200 µF and overall efficiency is up to 93%. They also feature a 600 kHz switching frequency, which offers the potential for improved transient response with reduction of output capacitance.
