IXS839 / IXS839A / IXS839B  
Synchronous Buck MOSFET Driver  
Features:  
General Description  
The IXS839/IXS839A/IXS839B are 2A Source / 4A  
Sink Synchronous Buck MOSFET Drivers. These  
Synchronous Buck MOSFET Drivers are specifically  
designed to drive two N-channel power MOSFETs  
in a synchronous buck converter. The High-Side  
driver is powered via a bootstrapped power  
connection. The driver is capable of 20ns High-Side  
output, and 18ns Low-Side output transition times  
driving a 3000pF load.  
Logic Level Gate Drive Compatible  
2A Source, 4A Sink Peak Drive Current  
Programmable High-Side Driver Turn-on Delay  
Supports Floating Voltage for Top Driver Up to  
24V  
IXS839/839B: Undervoltage Lockout  
IXS839A/B: Output Shutdown, Low Side  
Shutdown Inputs  
The IXS839 and IXS839B incorporate an  
undervoltage lockout to prevent unintentional gate  
drive output during low voltage conditions. The  
IXS83A/B include External Shutdown and Low-Side  
Drive Shutdown features. Simultaneous shutdown  
of both outputs prevents rapid output capacitor  
discharge. The high-side turn-on delay is adjustable  
with an external capacitor added at the DLY pin.  
10µA Shut Down Current  
2mA Quiescent Current (Non- Switching)  
Bootstrapped High Side Driver  
Cross-Conduction Protection  
Applications:  
Multiphase Desktop CPU Supplies  
Mobile CPU Core Voltage supplies  
The IXS839/839A/839B are designed to operate  
over a temperature range of -40°C to +85°C. The  
IXS839 is available in an 8-Lead SOIC, the  
IXS839A and the IXS839B in a 10-pin QFN.
