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.
