STEVAL-ISA109V2开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS规格书PDF中文资料

STEVAL-ISA109V2属于开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS。由意法半导体集团制造生产的STEVAL-ISA109V2评估板 - DC/DC 与 AC/DC（离线）SMPS该系列产品提供了一种方便的方法，可对开关模式电源转换所用的器件（包括 DC-DC 和 AC-DC 型）进行性能或特性评估。“稳压器”（包含内部电源开关装置）和“控制器”（设计为控制外部电源开关）之类的器件均包括在内。

描述 Description

The STEVAL-ISA109V2 is designed to aid in the

evaluation of the STBB2, a high efficiency buckboost DC-DC converter capable of providing

regulated output voltages in the range of 1.2 V to

5.5 V with an input voltage between 2.3 V and 5.5

V.

The board comes with the adjustable version of

the STBB2 pre-mounted, with the output voltage

set to 3.3 V. For this version, the VSEL pin must be

connected to VIN.

The board can also demonstrate the performance

of the fixed version of the STBB2, by replacing R1

with a 0 Ω resistor and disconnecting R2.

特性 Features
