ADP3650JRZ

ADP3650JRZ is a dual, high-voltage MOSFET driver optimized for driving two N-channel MOSFETs, the two switches in a non-isolated synchronous buck power converter. Each driver is capable of driving a 3000pF load with a 45ns propagation delay and a 25ns transition time. One of the drivers can be bootstrapped and is designed to handle the high-voltage slew rate associated with floating high-side gate drivers. The ADP3650 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs. The active-low OD pin shuts off both the high-side and the low-side MOSFETs to prevent rapid output capacitor discharge during system shutdown. Applications include telecom and datacom networking, industrial and medical systems, point of load conversion: memory, DSP, FPGA, ASIC.

• All-in-one synchronous buck driver, bootstrapped high-side drive
• One PWM signal generates both drives, anti-cross conduction protection circuitry
• Active-low OD for disabling the driver outputs, 250mV typ hysteresis at (VCC = 12V, BST = 4V to 26V)
• Input current is +1µA maximum at (VCC = 12V, BST = 4V to 26V)
• Supply voltage range from 4.15V to 13.2V at (VCC = 12V, BST = 4V to 26V)
• Supply current is 2mA typical at (BST = 12V, IN = 0V, VCC = 12V, BST = 4V to 26V)
• Propagation delay times (high side driver) is 45ns typical at (BST − SW = 12V, CLOAD = 3nF)
• SW pull-down resistance (high side driver) is 10Kohm typ at (SW to PGND, VCC = 12V, BST = 4V to 26V)
• Temperature range from -40°C to +85°C
• 8-lead SOIC-N package
