uP6019中文资料20W High Performance Single Synchronous Step-Up Converter数据手册uPI(UBIQ)规格书

描述 Description

The uP6019 is a high-efficiency, single synchronous boostconverter in Power Bank and E-Cigarette. The proprietaryRCOTTM technology provides fast transient response andhigh noise immunity. It supports ceramic output capacitors.This combination is ideal for building modern low duty ratio,untra-fast load step response DC-DC converters. The outputvoltage ranges from 4V to 15V, and the conversion inputvoltage ranges is from 3V to 5.5V. The switching frequencyis fixed 450kHz. It is available in a space saving WQFN4x4-26L package.
