44 / 52 page  Application information L5988D 44/52 DocID15324 Rev 4 In Figure 27 is shown an additional application example where the L5988D operates at a switching of 600 kHz. The designed system bandwidth is 73 kHz with a the phase margin of 51 . The peak current limitation is set 5.2 A, the valley current limitation 5.8 A in order to deliver up to 4 A DC to the load. Table 14. Component list application circuit (fSW = 400 kHz) Reference Part number Description Manufacturer C1 GRM32ER61E226KE15 Chip capacitor 22 µF 25 V Murata C10 GRM188R71E105KA12 Chip capacitor 1µF 25 V Murata C2A GRM32ER61C476KE15 Chip capacitor 47 µF 16 V C8 Chip capacitor 1 µF C3 Chip capacitor 330 nF C5 Chip capacitor 22 nF C6 Chip capacitor 1 nF C7 Chip capacitor 10 nF L1 744 311 470 Inductor 4.7 µH Wurth elektronik R1 Chip resistor 12 k ± 1% R2 Chip resistor 3.3 k ± 1% R3 Chip resistor 220 k ± 1% R5 Chip resistor 1.2 k ± 1% R6 Chip resistor 4.7 k ± 1% R7 Chip resistor 56 ± 1% R8 Chip resistor 4.7 k ± 1% R12 Chip resistor 5.6 R ± 1% U1 I.C.
