LT3697
pin FuncTions SYS (Pin 13):
The SYS pin is the second feedback input
BST (Pin 14):
The BST pin is used to provide a drive of the internal error amplifier. The SYS pin allows the voltage, higher than the input voltage, to the internal NPN LT3697 to regulate the output voltage at the output of a power switch. USB switch. If the USB switch goes open and the USB5V pin
SW (Pin 15, 16):
The SW pins are the output of the internal is no longer part of the control loop, the LT3697 regulates power switch. Connect these pins to the inductor, catch the SYS pin to 6.1V to protect the input of a USB switch diode, and boost capacitor. from an overvoltage condition. The SYS pin also supplies current to the internal regulator of the LT3697 and may
GND (Pin 17):
Ground. The exposed pad must be soldered be used to supply power to auxiliary circuitry. The active to the PCB. load also draws current from this pin to reduce output overshoot. This pin must be locally bypassed and must be tied to the switching regulator output. 3697f 10 For more information www.linear.com/LT3697
