Gate Driver ICs Forum Discussions

[The_BOOM]

We only need a unipolar positive DC voltage.
Can the IRA2153SD work with a simple two-winding transformer and a full-bridge rectifier?
What are the drawbacks?
Is there a different Infineon device that would work better in this configuration, such as a full-bridge gate-driver?

[Srivatsa]

The IRS2453D is a full bridge gate driver based on the IR2153D self-oscillating half-bridge gate driver IC.

[The_BOOM]

can the half-bridge driver work without a center-tap, by using appropriate rectifier?

[Srivatsa · Accepted solution]

Yes. The IC biasing conditions including the VCC should be met with the rectifier. See below application notes:
