产品概述 返回TOPQu0嘉泰姆

The CXSD62590 is a Power Management Unit (PMU) with 3 channels of high frequency synchronous Step-Down converters. Each channel is capable of delivering up to 3.5A output current and accepts input voltage from 2.6V to 5.5V. Each channel has an adaptive Constant-On-Time control scheme that achieves fast transient response while maintaininga constant switchingfrequency. It does not have the minimum on-time constrain normally a fixed-frequency current mode Step-down requires. Each channel can be independently turned ON/OFF by an enable pin providing flexibility for easy start-up sequencing. All three channel are packed into a small QFN4X4-24Lpackage greatly saving board space. CXSD62590 is available in a tiny QFN4X4-24Lpackage
