This document introduces the design of STEVAL-IPB001V1, a 2 W three-phase switch-mode power supply based on the STC04IE170HP ESBT. The power supply uses the UC3845B PWM driver and the STC04IE170HP ESBT as the main switch. It can be used to supply power to breaker applications and can be easily upgraded to higher output power.
The STEVAL-IPB001V1 is a demonstration board representing a complete solution for a 2 W single-output switched-mode power supply (SMPS). It is designed for breaker applications and can be easily upgraded for 3-phase power metering applications. The design utilizes the UC3845B PWM driver and the STC04IE170HP ESBT as the main switch.
