Description

General part information

UCD7230A Series

The UCD7230A is one in the UCD7k family of digital control compatible drivers for applications utilizing digital control techniques or applications requiring fast local peak current limit protection.

The UCD7230A is a MOSFET gate driver specifically designed for synchronous buck applications. It is ideally suited to provide the bridge between digital controllers such as the UCD91xx or the UCD92xx and the power stage. With cycle-by-cycle current limit protection, the UCD7230A device protects the power stage from faulty input signals or excessive load currents.

The UCD7230A includes high-side and low-side gate drivers which utilize Texas Instrument’s TrueDrive output architecture. This architecture delivers rated current into the gate capacitance of a MOSFET during the Miller plateau region of the switching. Furthermore, the UCD7230A offers a low offset differential amplifier with a fixed gain of 48. This amplifier greatly simplifies the task of conditioning small current sense signals inherent in high efficiency buck converters.
