conversion

Description

The STRG02 smart driver implements a control

scheme specific to secondary-side synchronous

rectification in STVCOT

™ based resonant

converters.

It provides two high current gate drive outputs,

each capable of driving one or more N-channel

low-side power MOSFETs. Both gate drivers are

controlled by the combination of the START input

and embedded predictive ZCD/ZVS control

assuring the two external power MOSFETs to be

switched in zero voltage / zero current conditions

to achieve high efficiency power conversion.

The high impedance mode can be configured with

the two external power MOSFETs immediately

kept OFF.

The STRG02 is available in a DFN12, 3 x 3 mm

package with an exposed pad.
