FUNCTION
Enable/Undervoltage-Lockout Pin. Drive to > 1.23V to start the devices. To externally program the UVLO
threshold of the input supply, connect a resistor-divider between input supply EN/UVLO and SGND.
Linear Regulator Output. Connect input bypass capacitor of at least 1μF from V CC to SGND as close as
possible to the IC.
Overvoltage Comparator Input. Connect a resistor-divider between the input supply (OVI) and SGND to
set the input overvoltage threshold.
Current-Limit Setting Pin. Connect a resistor between LIM and SGND to set the peak-current limit for
nonisolated flyback converter. Peak-current limit defaults to 500mA if unconnected.
Slope Compensation Input Pin. Connect a resistor between SLOPE and SGND to set slope-
compensation ramp. Connect to V CC for minimum slope compensation. See the Programming Slope
Compensation (SLOPE) section.
Inverting Input of the Flexible Error Amplifier. Connect to mid-point of resistor-divider from the positive
terminal output to SGND.
Flexible Error-Amplifier Output. Connect the frequency-compensation network between COMP and
SGND.
Soft-Start Pin. Connect a capacitor from SS to SGND to set the soft-start time interval.
Noninverting Input of the Flexible Error Amplifier. Connect to SS to use 1.22V as the reference.
No Connection
Internal 1.22V Reference Output Pin. Connect a 100pF capacitor from REF to SGND.
