FUNCTION
Boost Capacitor Connection. Connect a 0.1μF ceramic capacitor from BST to LX.
Internal Regulator Output. Bypass VD to GND with a 0.1μF ceramic capacitor.
Internal Connection. SGND must be connected to GND.
Output Sense Feedback Connection. For fixed output voltage (MAX5035A, MAX5035B, MAX5035C),
connect FB to V
OUT
. For adjustable output voltage (MAX5035D), use an external resistive voltage-divider to
set V
OUT
. V
FB
regulating set point is 1.22V.
Shutdown Control Input. Pull ON/
OFF
low to put the device in shutdown mode. Drive ON/
OFF
high for
normal operation.
