DC2598A

Demonstration circuit 2598A is a 60V 2MHz synchronous buck-boost controller featuring the LT®8390A. It accepts an input voltage from 4V to 24V (with transient to 60V) and regulates 12V output at up to 4A. DC2598A features high efficiency and 2MHz switching frequency, a high speed for a 4-switch buck-boost controller. It has PGOOD flag, short-circuit fault protection, ISMON current-monitoring output signal and spread spectrum frequency modulation (SSFM) or frequency synchronization. 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 adjustable switching frequency between 600KHz and 2MHz. Its high switching frequency is unique to buck-boost controller ICs. Because of this, it can be used for high power when the input may be above, below, or equal to the output.
