Schaltpläne und Formeln für Ripple Generation Methoden
Texas Instruments LM5163 SNVSBB3A - OCTOBER 2019 - REVISED APRIL 2024 Fsw(kHz) = Vout(V) * 2500 / R_ON(kOhm) Table 6-1. Ripple Generation Methods TYPE 1 Lowest Cost TYPE 2 Reduced Ripple TYPE 3 Minimum Ripple VIN SW LO VOUT CIN LM5163 BST FB R_ESR R_ON GND PGOOD CIN R_A R_FB C_OUT C_FF C_B RESR >= 20mV / (VFB1 * dIL(nom)) RESR >= VOUT / (2 * VIN * Fsw * COUT) CFF >= 1 / (2 * pi * Fsw * (RFB1 || RFB2)) RA * CA <= (VIN-nom - VOUT)
