*: PO = measured across the load using the following inductor:
COIL58120 MPPA 2 (magnectics) TURNS = 20 ø 1mm
(1) L = 15µH, C = 470nF
(3) ∆Gv is intended with R2, R17, R5, R9 1% precision
(4) FSW = 0.25 ⋅ (1/(300ns + R13 ⋅ ( C17 + 76pF) ⋅ 0.85)
(5) VRMAX = (+VCC) - (-VCC) when VR ≥VRMAX the device goes in Stand-By mode
