意法半导体广泛的脉宽调制(PWM)控制器产品组合可以支持隔离和非隔离的AC-DC和DC-DC开关电源 - 基于面向中高功率SMPS的单端(如反激式、正向或准谐振)和双端配置(如非对称半桥)中最流行的拓扑。
创新型PWM控制器确保更高的转换器效率和更低的设计成本
我们的PWM控制器产品包括众多高级数字控制器,采用创新型解决方案,可优化各种负载条件(特别是轻载条件)下的转换器效率,确保高电压启动。
这些PWM控制器IC还集成了完整的保护功能,即使在室外应用较宽的温度范围下,也可提高稳定性和可靠性。这样就减少了外部组件数量,使转换器的尺寸和成本最小化。
UC(电压模式)和SG(电流模式)系列的工业标准控制器也可用于更多主流的SMPS设计。

Compact quasi-resonant PWM controller for ultra-low standby power supplies
The STCH03 features a built-in high-voltage start-up circuit with zero power consumption, fully integrated blocks for primary-side constant-current output regulation and advanced power management, making it the best choice for high efficiency and ultra-low standby consumption power supplies with excellent dynamic performance.
Designed to provide a constant output current (CC) regulation using primary-sensing feedback, the STCH03 reduces BOM costs and simplifies your design as a dedicated current reference IC and current sensor are no longer required.
Moreover, an embedded frequency jitter technique helps reduce EMI noise.
