IMP38HC4 Product details

Description

Pin Number 8-Pin Package 1 2 3 4 14-Pin Package 1 3 5 7 Name COMP FB ISNS RT/CT Function Output of the Error amplifier and input to the PWM comparator.Inverting input of the Error Amplifier.Current sense comparator input.It is internally limited to 1V.Oscillator RC timing component connection.Resistor RT is connected to VREF and capacitor CT is connected to ground.Different values of RT and CT determine the maximum duty cycle.Combined power and analog ground for 8-pin packaged devices
