MAX1535AETJ中文资料美信数据手册PDF规格书

General Description

The MAX1535A is a highly integrated, multichemistry battery charger that simplifies construction of advanced smart chargers with a minimum number of external components. It uses Intel’s system management bus (SMBus) to control the charge voltage, charge current, and the maximum current drawn from the AC adapter. High efficiency is achieved through use of a constant off time step-down topology with synchronous rectification.
