Description

The LM63615-Q1 is a synchronous buck converter with a wide input voltage range from 3.5 V to 36 V and maximum output current of 1.5 A.

The LM63615-Q1 can be configured as an inverting buck-boost (IBB) converter with a negative output voltage.

This application note demonstrates how the LM63615-Q1 can be used as an inverting buck-boost converter, along with optional design considerations for inverting buck-boost converters such as a PGOOD or EN level-shifter.

If higher output current is required, the LM63615-Q1 is pin-to-pin compatible with the 2.5-A rated LM63625-Q1 and the 3.25-A rated LM63635-Q1.

The LM63615-Q1 is also pin-to-pin compatible with 1-A rated LM63610-Q1.
