STEVAL-ISA110V1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-ISA110V1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-ISA110V1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-ISA110V1 demonstration board is a

12 V-1 A power supply set in non-isolated flyback

topology using the VIPER26LN, a new offline

high-voltage converter by STMicroelectronics.

The features of the device include an 800 V

avalanche-rugged power section, PWM operation

at 60 kHz with frequency jittering for lower EMI,

current limiting with adjustable set point, onboard

soft-start, a safe auto-restart after a fault

condition, and low standby power.

Protection features include thermal shutdown with

hysteresis, delayed overload protection, and open

loop failure protection.
