U6110 is a low cost, highly integrated PWM
power switch for non-isolated buck and buck-boost applications.
U6110 combines a 500V power MOSFET with the ON/OFF PWM controller in one chip. The IC can achieve high precision 5V default Output at universal AC input. In U6110, PWM switching frequency with shuffling is fixed to 31KHz. The IC has built-in green mode control for light and zero loadings, which can achieve less than 50mW standby power.
U6110 integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), On-chip Thermal Shutdown (OTP), Over Load Protection (OLP) Short Load Protection (SLP), etc.
