EST.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.
