TERMINAL FUNCTIONS PIN Fucntion Table TERMINAL I/O DESCRIPTION QFN TSSOP NAME 24 24 Supply input for high-side NFET driver. Bypass to SWx with a high-quality VBST1, 23, 8 2, 11 I 0.1-mF ceramic capacitor. An external schottky diode can be added from VBST2 VREG5 if forward drop is critical to drive the high-side FET. EN1, EN2 24, 7 3, 10 I Enable. Pull High to enable SMPS. Output voltage inputs for on-time adjustment and output discharge. Connect VO1, VO2 1, 6 4, 9 I directly to the output voltage. VFB1, 2, 5 5, 8 I D-CAP2 feedback inputs. Connect to output voltage with resistor divider.
