Wolfson unveils 'world's highest' current monolithic PMIC
1 min read
Wolfson Microelectronics has launched what it says is the world's highest current monolithic power management IC (PMIC).
According to Wolfson, the WM8325 power management subsystem delivers a cost-effective, flexible solution for portable multimedia applications including tablets, e-books, media players and smartphones.
It features four programmable dc/dc converters - including one which is capable of delivering up to 2.5A - and 11 LDO regulators, four of which are low noise for supplying sensitive analogue subsystems.
The optimised QFN package is designed to improve thermal performance and reduce parasitic components, enabling low cost four layer pcb manufacturing. Wolfson says the package allows large pcb tracks for all high current paths, which improves transient performance.
Wolfson claims that its low thermal resistance (24oC/W), lower electrical resistance and improved dc/dc technology, enables over 5% improvement in efficiency (at 1A) when compared with previous generations of PMIC dc/dc converters.
The WM8325 is available for sampling now in an 8 x 8mm, 0.85mm thick, 81 lead QFN package.
