The U6203SH is an AC-DC controller & regulator manufactured by UNI-SEMI, with RoHS compliance. It is a System-On-Chip (SoC) solution used for the control and regulation of AC-DC power supplies and motor control. This part is a SOP-8 (Small Outline Package 8) that features a full control functionality including cycle-by-cycle current limit, constant frequency internal oscillator, power good flag indicator, over-current flag indicator, thermal device temperature monitoring, and under-voltage lockout. It also has dual on-chip signal conditioning stages and an advanced, yet simple, power management control algorithm to achieve superior performance in all applications. The U6203SH also has comprehensive outputs, with low-cost and reliable direct drive from both PWM and control signals to external components.
