STEVAL-IHT005V2，基于 STM32F100 MCU 的全 3.3V ACS/Triac 控制演示板

使用 STMicroelectronics 的 VIPER16L 的參考設計

設計簡介

STEVAL-IHT005V2，演示板被設計為家用電器應用的完整解決方案。特別強調在 IEC61000-4-4（突發）測試期間基于 A 類 4 kV 電平演示強大的完整 3.3V 解決方案。該板還允許設計人員評估使用 3.3V 電源進行交流開關控制的可行性。 STEVAL-IHT005V2 基于最近推出的 48 引腳、32 位 STM32F100C4T6B MCU，運行頻率為 24 MHz（RC 用戶可調整的內部 RC 時鐘），具有 16 KB 閃存、12 位 A/D 轉換器、5 個定時器、通信接口和 4 KB SRAM。電源電路基于 VIPer16L，這是一種離線轉換器，具有 800 V 耐雪崩電源部分，工作頻率為 60 kHz。電源以降壓-升壓拓撲提供負 6V

說明

STEVAL-IHT005V2, Demonstration Board is designed as a complete solution proposal for home appliance applications. Special emphasis is placed on demonstration of a robust full 3.3V solution, based on 4 kV level in class A during an IEC61000-4-4 (burst) test. The board also allows designers to evaluate the feasibility of AC switch control with 3.3V supply. STEVAL-IHT005V2 is based on the recently-introduced 48-pin, 32-bit STM32F100C4T6B MCU running at 24 MHz (RC user-trimmable internal RC clock), featuring 16 Kbytes of Flash memory, 12-bit A/D converter, 5 timers, communication interfaces, and 4 Kbytes of SRAM. The power supply circuitry is based on the VIPer16L, an offline converter with an 800 V avalanche-rugged power section, operating at 60 kHz. The power supply provides negative 6V in buck-boost topology
