The NCP5355D is a high-performance, dual MOSFET gate driver designed by ON Semiconductor, tailored for effectively driving the gates of both high-side and low-side power MOSFETs in synchronous buck converters. This device is optimized for high-frequency operation, making it an excellent choice for modern power supply applications where efficiency and compact design are critical.

Key Features

• High Drive Capability: The NCP5355D boasts a robust drive strength capable of delivering peak currents of up to 2A for the high-side and low-side MOSFETs, ensuring fast switching times and reduced power loss.
• Adaptive Non-Overlap Control: To prevent potentially damaging simultaneous conduction, the NCP5355D features adaptive non-overlapping gate drive control, enhancing the reliability and longevity of the power stage.
• Wide Supply Voltage Range: With an operating range from 4.5V to 13.2V, the NCP5355D is versatile and can accommodate a broad spectrum of power systems.
• Under-Voltage Lockout (UVLO): The integrated UVLO feature ensures that the gate driver operates only when the supply voltage is sufficient, safeguarding the MOSFETs from insufficient gate voltage.
• Thermal Shutdown Protection: To protect against overheating, the NCP5355D includes a thermal shutdown mechanism that disables the driver when the junction temperature exceeds the threshold.
