What are the key protection features?

It includes start-up overcurrent protection, overcurrent protection (OCP), thermal shutdown (TSD), and protection against LED open and short circuits.

Does it require external loop compensation?

No, the MBI6655 uses a Hysteretic PFM architecture, which simplifies the design by eliminating the need for external loop compensation components.

What is the input voltage range?

The device supports an input voltage range of 6V to 36V.

What is the pinout of MBI6655GSB-B?

Use the MBI6655GSB-B datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about MBI6655GSB-B pinout to locate pins, power rails, and interface signals before layout.
