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. http://onsemi.com MARKING DIAGRAM WDFN8 CASE 511AQ GN MG G GN = Specific Device Code M = Date Code G = Pb−Free Device PIN CONFIGURATION General Features • • • • • • • • • • 1 1 Provides Peak EMI Reduction Companion IC for RT−CT or a RT based PWM Controllers Supports PWM Switching Frequency up to 5 MHz Analog Deviation Selection External or Internal Analog ModRate Selection Option Supply Voltage: 3.3 V $ 0.3 V Dynamic Supply Current less than 5 mA @ 1 MHz Operating Temperature Range: 0°C to +70°C 8 pin , WDFN(2 mm x 2 mm) Package These Devices are Pb−Free and are RoHS Compliant RT−CT/RT 1 MREXTR 2 NC 3 GND 4 8 VDD 7 MRSEL 6 NC 5 SSEXTR ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 4 of this data sheet.
