The IR4426STRPBF is an IC (integrated circuit) component developed by Infineon Technologies. It belongs to the category of synchronous buck MOSFET (metal-oxide-semiconductor field-effect transistor) drivers and offers various key features.
One of the primary functions of the IR4426STRPBF is to drive external power MOSFET switches in synchronous rectified buck converters. This IC acts as an efficient control unit for DC-DC power supplies, helping to regulate voltage conversion in different applications.
Key features:
1. High-side and low-side drivers: The IR4426STRPBF provides a high-side and low-side MOSFET driver, which enables it to drive both power MOSFETs in the synchronous buck converter. This feature ensures that the IC can handle the complete switching cycle efficiently.
2. Integrated bootstrap diode: The IC includes an integrated bootstrap diode that simplifies the design by eliminating the need for an external diode. This diode is essential for generating a power supply voltage above the input voltage for efficient high-side driving.
3. Logic inputs: The IC features logic inputs for various control signals, such as ENABLE, SOFTS, and COMPH. These inputs allow external control circuits to provide the necessary signals for enabling or disabling the synchronous buck converter, adjusting the delays, and controlling the output voltage
