NCP5358

NCP5358 Gate Driver for Desktop Power Systems The NCP5358 is a high performance two channel gate driver. It combines two single NCP5359 gate drivers together and provides an optimized solution for multi−phase application. Each channel gate driver has both high−side and low side power MOSFETs in a synchronous buck converter. Also, it can drive up to 3 nF load with a 25 ns propagation delay and 20 ns transition time. An adaptive non−overlap and power saving operation circuit has built in. It can provide a low switching loss and high efficiency solution in notebook and desktop systems. Thus, this controller has three protection functions, under voltage lockout (UVLO), over voltage protection (OVP) and thermal shutdown. The NCP5358 is available in 4x4 mm QFN16 package. Features Faster Rise and Fall Times Thermal Shutdown Protection Adaptive−Non−Overlap Circuit Floating Top Driver Accommodates Boost voltage of up to 30 V Output Disable Control Turn Off Both MOSFETs Complies with VR11.1 Specifications Under−Voltage Lock Out Power Saving Operation under Light Load Condition Thermally Enhanced Package Available These are Pb−Free Devices Typical Applications Power Solutions for Desktop and Notebook system. http://onsemi.com MARKING DIAGRAM QFN−16 CASE 485D 4x4 mm N5358 ALYWG G N5358 A L Y W G = Device Code = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package PIN CONNECTIONS EN PWM1 PWM2 GND VCC SW1 DRVH1 BST1 SW2 DRVH2 BST2 VCCP DRVL2 P...
