LTC3563
U U U PI FU CTIO S VOUT (Pin 1):
Output Voltage Feedback. An internal resistive
VSEL (Pin 5):
Output Voltage Selection Pin. This pin controls divider divides the output voltage down for comparison the regulated output voltage. When tied to GND, VOUT is to the internal 0.6V reference voltage. 1.28V. When fl oating or connecting this pin to VIN, VOUT becomes 1.87V.
VIN (Pin 2):
Power Supply Pin. Must be closely decoupled to GND.
RUN (Pin 6):
Converter Enable Pin. Forcing this pin above 1.5V enables this part, while forcing it below 0.3V causes
GND (Pin 3):
Ground Pin. the device to shut down. In shutdown, all functions are
SW (Pin 4):
Switch Node Connection to Inductor. This pin disabled drawing <1µA supply current. This pin must be connects to the drains of the internal main and synchronous driven; do not fl oat. power MOSFET switches.
Exposed Pad (Pin 7):
GND. The Exposed Pad is ground. It must be soldered to PCB ground to provide both electrical contact and optimum thermal performance. 3563f 6
