Description

The TMI3342 is a high efficiency 370kHz switching

frequency synchronous Buck DC-DC converter

with capability of delivering up to peak 2A current.

TMI3342 integrates both high and low side switch

with low RDS(ON) to minimize the conduction loss.

Low output voltage ripple and small external

inductor and capacitor size are achieved with

370kHz switching frequency.

The TMI3342 requires a minimum number of

external components and

it is available in a 6-pin

SOT23-6 RoHS compliant package.
