controlled with respect to the internal error-voltage level (output
power) to allow the converter to maintain output voltage
regulation and relatively flat conversion efficiency between 10%
to 100% of rated load which is essential to meet many efficiency
directives.
The degree of frequency slide is also controlled as a function of
peak input line voltage, at high input line the maximum off-time
voltage reference at zero error-voltage will be approximately 1/2
of the maximum value at low input line conditions.
The lower V OFF slope reduces the average frequency swing for
high input line operation.
Protection Modes
VOLTAGE MONITOR (V) Pin Shutdown
The VOLTAGE MONITOR pin features a shutdown protection
mode which can be used with the VOLTAGE MONITOR pin
resistor or external circuitry to cover system faults. During
start-up (1 V < V FB < 5.8 V) in the event the current through the
www.powerint.com
VOLTAGE MONITOR pin exceeds the I V(OFF) threshold for a
duration exceeding approximately (1 m s), the IC disables the
internal MOSFET for the entire duration that the V pin current is
above I V(OFF) . In normal operation, if the current through the V
pin exceeds the I V(OFF) threshold for a duration exceeding t V(OFF) ,
the IC will re-initiate the start-up sequence.
Brown-In Protection (I UV+ )
The VOLTAGE MONITOR pin features an input line undervoltage
detection to limit the minimum start-up voltage detected
through the V pin. This detection threshold will inhibit the
device from starting at very low input AC voltage.
Brown-Out Protection (I UV- )
The V pin features a brown-out protection mode wherein the
HiperPFS will turn-off when the V pin current is below the Line
UV-threshold for a period exceeding the t REFRESH time period. In
the event a single half-line cycle is missing (normal operating
line frequency is 47 to 63 Hz) the brown-out protection will not
be activated. The HiperPFS shutdown in effect gradually
reduces the internal error-voltage to zero volts at rate of 1 V/ms
