MAX5035
1A, 76V, High-Efficiency MAXPower Step-Down DC-DC Converter Pin Description PIN NAME FUNCTION
1 BST Boost Capacitor Connection. Connect a 0.1µF ceramic capacitor from BST to LX. 2 VD Internal Regulator Output. Bypass VD to GND with a 0.1µF ceramic capacitor. 3 SGND Internal Connection. SGND must be connected to GND. Output Sense Feedback Connection. For fixed output voltage (MAX5035A, MAX5035B, MAX5035C), 4 FB connect FB to VOUT. For adjustable output voltage (MAX5035D, MAX5035E), use an external resistive voltage-divider to set VOUT. VFB regulating set point is 1.22V. 5 ON/OFF Shutdown Control Input. Pull ON/OFF low to put the device in shutdown mode. Drive ON/OFF high for normal operation. 6 GND Ground 7 VIN Input Voltage. Bypass VIN to GND with a low ESR capacitor as close to the device as possible. 8 LX Source Connection of Internal High-Side Switch
