丨产品介绍丨
Holtek新推出电源逆变器MCU，发布HT45F7550的两款SPWM与硬件乘除法器实现DC-AC纯正弦波逆变控制，搭配HT45R7130的电源PWM与Gate Driver实现DC-DC升压控制，组合为纯正弦波逆变器模块，逆变适用于储能箱等产品。发布
HT45F7550具备8KW Flash ROM、两款512 Bytes RAM，电源独立PWM RAM Sector供PWM自动查表，逆变生成50Hz或60Hz正弦波，发布并整合硬件乘除法器优化响应速度，两款HT45R7130具备2KW OTP ROM、电源128 Bytes RAM，逆变PWM IP适用于1000W以下主流的发布推挽变压器架构，内建LDO，两款缩小PCB尺寸，电源提高整机功率密度，2个MCU皆内建12-bit ADC、OPA、比较器实现各项保护功能，形成完整且安全的逆变器解决方案。
HT45R7130提供16-pin NSOP封装、HT45F7550提供24-pin SSOP及28-pin SSOP封装可供选择。
