Application Notes
(1) The input line for AMP A and AMP B is shared with VIN1.
(2) AMP A and AMP B are on in normal use.
(3) The output voltage is 5 V when an external NPN transistor has been added.
(4) Depending on the type, load current and connection position (distance from the LA5612) of the external NPN transistor, the
value of a capacitor connected between emitter and ground must be changed for stable operation.
(5) The capacitors connected between each pin and GND are bypass capacitors for preventing oscillation: as such, they must be
positioned as close to the LA5612 as possible in order to stabilize operation.
