Sn51dp: Datasheet Pdf _verified_

This circuit operates as a switch-mode power supply (SMPS), stepping up the input voltage to the required level for driving the LED backlight strings.

Output drive signal routed directly to the external switching MOSFET. GND Common reference ground for the circuit assembly. 5 CS

This is the most popular application. Connect the relay coil between V+ (e.g., 24V) and the output pin. Connect the COM pin to the same V+. The internal diode will clamp inductive kickback. sn51dp datasheet pdf

Pin 9 (COM) must be connected to the positive supply of the load whenever inductive loads are used. This allows the internal clamp diodes to safely dissipate back-EMF.

Limits current through the external MOSFET via the CS (Current Sense) pin. This circuit operates as a switch-mode power supply
