The SYVL927 is a high voltage synchronous buckboost converter. The device operates over a wide input voltage range from 4V to 40V. The SYVL927 offers two operational modes, PSM and FCCM, under light load condition. The four-integrated low RDS(ON) switches minimize the conduction loss.

The SYVL927 features external soft-start, enable control, open drain power good indicator and 1uA shutdown current. The SYVL927 also includes full protection features, such as output over current/short circuit protection, over voltage protection and thermal shutdown for reliable operating.

The device is available in compact QFN5×5-30 package.
