Current Sense Circuit Peak current (IS) is equaled: IS(MAX)=1.0V/RS There should be a small RC filter to suppress switch transients. Oscillator Waveforms and Maximum Duty Cycle 8 5 4 VREF RT/RC GND CT RT INTERINAL CLOCK INTERINAL CLOCK V4 V4 LARGE RT SMALL CT SMALL CT LARGE RT CT (Oscillator timing capacitor) can be charged by VREF through RT and discharged by an internal current source. At discharge time, the internal clock signal blanks the output to the low. Both oscillator frequency and maximum duty cycle can be determined by Selection of RT and CT. All charge and discharge times can be calculated by the next formulas: tC=0.55 RT CT tD=RTCTIn ⎟⎟ ⎠ ⎞ ⎜⎜ ⎝ ⎛ − − 4 0.0063R 2.7 0.0063R T T |
