11 / 24 page www.ti.com APPLICATION INFORMATION Zi Zf VFB COMP 2.5 V 0.5 mA Error Amplifier + − RS Cf Rf Error Amplifier 2R R 1 V Current-Sense Comparator IS (see Note A) + − ISENSE COMP GND CT RT VREF RT/CT GND TL284xB, TL384xB HIGH-PERFORMANCE CURRENT-MODE PWM CONTROLLERS SLVS610B – AUGUST 2006 – REVISED JULY 2007 The error-amplifier configuation circuit is shown in Figure 1. A. Error amplifier can source or sink up to 0.5 mA. Figure 1. Error-Amplifier Configuration The current-sense circuit is shown in Figure 2. A. Peak current (IS) is determined by the formula: IS(max) = 1 V/RS B. A small RC filter formed by resistor Rf and capacitor Cf may be required to suppress switch transients. Figure 2. Current-Sense Circuit The oscillator frequency is set using the circuit shown in Figure 3. The frequency is calculated as: f = 1 / RTCT For RT > 5 kΩ: f ≈ 1.72 / R TCT Figure 3.
