6105 PWM POWER SUPPLY SUPERVISOR WITH REGULATOR Description The EST6105 is designed with a pulse-width-modulation control circuit, 2 sets of TL431 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 voltages.
OVP (Over voltage protection) function is for +3.
3V, +5V, +12V voltages.
OPP (Over power protection), NVP (Negative voltage protection) are over power and negative voltages.
UVAC (Under voltage AC protection) is for the main AC under voltage check or fail detection.
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.
2 sets of TL431 shunt regulators are for stable reference voltage outputs.
Push-pull PWM output and soft start function are supported.
Pin Configuration (Top View) Features „ 3-channel under voltage protection (UVP) „ 3-channel over voltage protection (OVP) „ 1-channel over voltage protection (OPP) „ 1-channel negative voltage protection (NVP) „ 1-channel under voltage AC protection (UVAC) „ Remote on/off control function with debounce time (REM) „ Dual output for push-pull operation (OP1/OP2) „ Soft start capability by external capacitor (SS) „ 2 sets of internal TL431 shunt regulators Ordering Information Order Number EST6105D20 Package PDIP-20 (RoHS) Packing Tube Top Marking EST6105D www.
