These two single-channel dc-dc step-down power modules deliver high power density and up to 95% efficiency in a compact 4.5- x 7.5- x 1.85-mm footprint. The pin-compatible 5-A ISL8205M and 3-A ISL8202M modules provide point-of-load (POL) conversions for FPGAs, DSPs and MCUs in a range of products, including portable industrial equipment that uses Li-ion batteries. The modules are complete power supplies that include a controller, MOSFETs, inductor and passive components inside an encapsulated module. With a height of 1.85 mm, the modules can be mounted directly on the backside of a PCB, freeing up space for topside-mounted components.
