STEVAL-ISA129V1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-ISA129V1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-ISA129V1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-ISA129V1 demonstration board is a

16 V - 280 mA application set in non isolated

flyback topology using the VIPer16, a new off-line

high voltage converter by STMicroelectronics.

The VIPer16 features an 800 V avalanche rugged

power section, PWM operation at 115 kHz with

frequency jittering for lower EMI, limiting current

with adjustable set point, on-board soft-start, and

safe auto-restart after a fault condition.

Moreover, the VIPer16 can work with or without

the auxiliary winding. In the former case, it can

reach very low standby consumption (< 50 mW at

265 Vac), while in the latter the IC is supplied by

an internal current generator, thus eliminating the

cost of the transformer auxiliary winding.

• Protection features available include thermal

shutdown with hysteresis and delayed

overload protection.
