uP1741中文资料8A High Voltage Synchronous Buck Converter数据手册uPI(UBIQ)规格书

描述 Description

The uP1741P is a high performance synchronous buckconverter. The synchronous buck of the uP1741P adoptsuPI proprietary robust constant on-time (RCOTTM) PWMscheme that features easy-to-use, low external componentcount, fast transient response and quasi-constantfrequency operation over the operation range.

The uP1741P has complete functions including undervoltage protection, over current protection, over voltageprotection, power-up sequencing, power OK output, andthermal shutdown. The uP1741P is available in WQFN4x4-32L package.
