Power Management Chip

Depending on the technical accumulation and deep understanding of circuit topology and control strategy, the company defines and develops a variety of power management chips, covering the main controller, driver chip, auxiliary source chip and POL chip. The chips are with the features of MHz level multi-mode precise control and high frequency low delay high current drive capability, adopting WLCSP wafer-level package, which can greatly reduce the control circuit board area, solving the problem of high power integration and miniaturization,provide "core" support for the company's high-end module power supply what is completely made in China.
