NCP5339 Datasheet, PDF (1/13 Pages) ON Semiconductor – Integrated Driver & MOSFETs

NCP5339
Integrated Driver &
MOSFETs
The NCP5339 integrates a MOSFET driver, high−side MOSFET
and low−side MOSFET into a 6 mm x 6 mm 40−pin QFN package.
The driver and MOSFETs have been optimized for high−current
DC−DC buck power conversion applications. The NCP5339
integrated solution greatly reduce package parasitics and board space
compared to a discrete component solution.
Features
• 3−State 5 V PWM Logic
• Capable of Switching Frequencies up to 1 MHz
• Zero Current Detection for Improving Light Load Efficiency
• Internal Bootstrap Schottky Diode
• Undervoltage Lockout of VCIN
• Disable Pin Disables Both Driver Outputs
• Internal Thermal Warning / Thermal Shutdown Functionality
• These are Pb−free Devices
Typical Applications
• Servers and Desktops
• Graphics Cards
• Telecom
