Synchronous Rectified Buck MOSFET Drivers  
ISL6625A  
The ISL6625A is a high frequency MOSFET driver designed to  
drive upper and lower power N-Channel MOSFETs in a  
synchronous rectified buck converter topology.  
Features  
• Dual MOSFET drives for synchronous rectified bridge  
• Advanced adaptive zero shoot-through protection  
- PHASE detection  
In ISL6625A, the upper and lower gates are both driven to an  
externally applied voltage. This provides the capability to  
optimize applications involving trade-offs between gate charge  
and conduction losses.  
- LGATE detection  
- Auto-Zero of r  
DS(ON)  
conduction offset effect  
• Low standby bias current  
• 36V internal bootstrap switcher  
• Bootstrap capacitor overcharging prevention  
An advanced adaptive shoot-through protection is integrated to  
prevent both the upper and lower MOSFETs from conducting  
simultaneously and to minimize dead time. The ISL6625A has  
a 10kΩ integrated high-side gate-to-source resistor to prevent  
self turn-on due to high input bus dV/dt.  
• Integrated high-side gate-to-source resistor to prevent from  
self turn-on due to high input bus dV/dt  
• Pre-POR overvoltage protection for start-up and shutdown  
• Power rails undervoltage protection  
This driver also has an overvoltage protection feature, which is  
operational while VCC is below the POR threshold. The PHASE  
node is connected to the gate of the low-side MOSFET (LGATE)  
via a 30kΩ resistor, limiting the output voltage of the converter  
close to the gate threshold of the low-side MOSFET. This is  
dependent on the current being shunted, which provides some  
protection to the load should the upper MOSFET(s) become  
shorted.  
• Expandable bottom copper pad for enhanced heat sinking  
• Dual flat no-lead (DFN) package  
- Near chip-scale package footprint; improves PCB  
efficiency and thinner in profile  
• Pb-Free (RoHS compliant)  
Applications  
• High light load efficiency voltage regulators  
• Core regulators for advanced microprocessors  
• High current DC/DC converters
