P6P82PS01A
Peak EMI Reduction Device
for Power Systems
Functional Description
P6P82PS01A is a versatile, 3.3 V Peak EMI reduction device.
P6P82PS01A can be interfaced/connected to the PWM frequency
controlling node (either RT−CT or RT) to modulate the switching
frequency of the PWM controller which in turn reduces the Peak EMI
of the power system.
P6P82PS01A has an SSEXTR pin to select different frequency
deviations depending upon the value of an external resistor connected
between SSEXTR and GND.
MRSEL selects an external or an internal analog Modulation Rate
clock. When MRSEL is pulled LOW, different moulation rates can be
selected depending upon the value of an external resistor connected
between MREXTR and GND. When MRSEL pin is pulled HIGH, an
external Modulation clock can be fed through MREXTR pin. Refer
Modulation Rate Selection table.
P6P82PS01A operates from a 3.3 V $ 0.3 V supply, and is
available in an 8 pin WDFN(2 mm x 2 mm) package.
