uP6055中文资料20W High Performance, Single Synchronous Step-Up Controller数据手册uPI(UBIQ)规格书

描述 Description

The uP6055 is a high-efficiency, single synchronous boostcontroller suitable for up to 20W applications in Power Bankand E-Cigarette. The proprietary RCOTTM technologyprovides fast transient response and high noise immunity.It supports ceramic output capacitors. This combination isideal for building modern low duty ratio, untra-fast load stepresponse DC-DC converters. The output voltage rangesfrom 4V to 13V, and the conversion input voltage ranges isfrom 3V to 5.5V. The switching frequency is fixed 500kHz.It is available in a space saving VQFN3x3-16L package.
