STEVAL-IHT005V2, Full 3.3V ACS/Triac Control Demonstration Board based on STM32F100 MCUs
Desain referensi oleh: STMicroelectronics
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
