SW Pin Equivalent Circuit Diagram
1. Power switch
On when power switch is grounded
IO =VCC/200k+VCC – 0.7 V/22 k
Pin 38
VS = 100 mV or less
2. Power mute and low boost switch
On when pin 37 power mute is grounded
On in pin 41 low boost switch floating mode
IO = 0.1 A or less
VS = 80 mV or less
* The discharge resistance for
smoothing is 430 k
max.
