TDA7490L
*: Po = measured across the load using the following inductor: COIL58120 MPPA 2 (magnectics) TURNS= 20
1 mm
(1) L = 15H, 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
