VSMC’s VS8801L with Adaptive ASPWM Controlled Technology, by driving up to eight PWM converter channels in sequence, provides a new and effective tool for power-management control of new generations of portable devices such as: smartphones, PDAs, MP4-players … This controller familly are designed to offer advanced specifications which are fully adapted to common and particular demands from portable device designers.

With up to eight phases, each capable of up to 1MHz operation, the VS8801L can be used to build 8 separate channels of DC/DC converters that provide energy to various types of load with excellent efficiency, low ripples, and with lowest external component count.

For energy-saving reasons while all the loads is turned off, the VS8801L offers a stand-by mode, where the quiescent current does not exceed 50μA typically. In this stand-by mode just the stand-by LDOs remain active.
