    LW4933 POWER SUPPLY SUPERVISOR WITH PWM CONTROLLER Description The LW4933 is designed with a pulse-width-modulation control circuit and a complete power supervisor for use in the switched mode power supply . It contains various functions, like under voltage protection (UVP), over voltage protection (OVP), power good output (PG) and ON/OFF control (REM). UVP(Under voltage protection) function is for +3.3V, +5V, +12V outputs. OVP(Over voltage protection) function is for +3.3V, +5V, +12V and PT is for extra protection input. PG(Power good signal) is a safe operation signal to inform the external parts. REM(Remote on/off) is used to control the SMPS on/off. The REM control signal has the on/off transferred debounce–time.
