概要
The design implemented in the STEVAL-IPB001V1 demonstration board represents a complete solution for a 2 W single-output SMPS (switched-mode power supply), which is widely used to supply power in breaker applications.
The SMPS employs the UC3845B PWM driver, and uses the STC04IE170HP ESBT as the main switch.
This design can also be applied to power supplies for 3-phase power metering applications, as it can be easily upgraded for higher output power.
