TCS3815
2.5MHz,Fixed-Output Synchronus Boost Regulator
产品描述
The is a low-power boost regulator designed to provide a minimum voltage-regulated rail from a standard single-cell Li-Ion battery and advanced battery chemistries. Even below the minimum system battery voltage, the device maintains the output voltage regulation for a minimum output load current of 1A. The combination of built-in power transistors, synchronous rectification, and low supply current suit the for battery-powered applications.
The is available in a 9-bump, 0.4mm pitch, WLCSP.
