产品详情

The evaluation circuit EVAL-LT8390A-AZ is a synchronous 4-switch buck-boost controller featuring the LT8390A and 4 EPC GaN FETs. This circuit outputs 24V and maintains tight regulation with up to 5A load current and over an input voltage from 8V to 60V. 2MHz switching frequency provides a small footprint using a single 6mm x 6mm x 6mm inductor while maintaining high efficiency.

The LT8390A features a 5V gate driver that is used to safely drive GaNFETs. Additionally, the EVAL-LT8390A-AZ board features external clamping circuitry around the bootstrap capacitors to guarantee that the gate drive of the top FETs is driven under the absolute maximum gate-to-source voltage of the GaNFET. Additionally, Schottky diodes are placed anti-parallel to the synchronous GaNFETs to help with reverse conduction during the LT8390A’s 25ns dead time.

The LT8390A has a wide input voltage range from 4V to 60V. It can regulate an output as a boost, a buck, or a 4-switch boost-buck controller. It has an adjustableswitching frequency between 600kHz and 2MHz. It has anoption for external frequency synchronization or spreadspectrum frequency modulation. Its high switchingfrequency is unique to buck-boost controller ICs. Becauseof this, it can be used for high power when the input maybe above, below, or equal to the output.

The LT8390A data sheet gives a complete description of the part, operation, and applications information. The data sheet must be read in conjunction with this user guide. The LT8390AJUFD is assembled in a 28-lead 4mm x 5mm plastic QFN package with a thermally enhanced ground pad. LT8390A is also available in a 28-Lead plastic TSSOP (FE) package. Proper board layout is essential for maximum thermal performance. Refer to the data sheet PC Board Layout Checklist section for more details.
