note)The circuit diagram and the values are only tentative which are subject to change.
* : Make sure that the capacitors of the output pins are 10
μF or higher and ESR is 10 or lower in total and temperature characteristics and accuracy are taken
into consideration. Also the E-cap should have good high frequency characteristics.
USB output voltage setting method
Formula for USB voltage calculation
USB =
1.26[V]
R1
× R2 + 1.26[V]
R2
R1 =
(USB-1.26)
1.26
Please design so that the ratio of R1 and R2 may fill the
above-mentioned expression for the set USB voltage.
R2
R1 =
(5.0-1.26)
1.26
2.968
R2
R1 =
27k
9.1k
2.967
The FB voltage is determined by the internal
band gap voltage of the IC (typ = 1.26V)
USB = 1.26V
× 2.967 + 1.26V 4.998V
