Caution Set the CS voltage so that the switch voltage (V_SW1) is equal to or greater than the RESET
detection voltage (−V_DET2).
Remark 1 The selection range is as follows.
V_RO, VOUT, VCH: 2.3 to 5.4 V (0.1 V steps)
−VDET1:
2.4 to 5.3 V (0.1 V steps)
−VDET2:
1.7 to 3.4 V (0.1 V steps )
V_SW1:
+V_DET1 × 0.85 or +V_DET1 × 0.77
