ISL6207 Data Sheet December 2, 2005 FN9075.8 High Voltage Synchronous Rectified Buck Features MOSFET Driver Drives Two N-Channel MOSFETs The ISL6207 is a high frequency, dual MOSFET driver, Adaptive Shoot-Through Protection optimized to drive two N-Channel power MOSFETs in a synchronous-rectified buck converter topology in mobile 30V Operation Voltage computing applications. This driver, combined with an Intersil 0.4 On-Resistance and 4A Sink Current Capability Multi-Phase Buck PWM controller, such as ISL6223, ISL6215, and ISL6216, forms a complete single-stage core-voltage Supports High Switching Frequency regulator solution for advanced mobile microprocessors. - Fast Output Rise Time - Short Propagation Delays The ISL6207 features 4A typical sink current for the lower gate driver. The 4A typical sink current is capable of holding the Three-State PWM Input for Power Stage Shutdown lower MOSFET gate during the Phase node rising edge to Internal Bootstrap Schottky Diode prevent the shoot-through power loss caused by the high dv/dt of the Phase node. The operation voltage matches the 30V QFN Package: breakdown voltage of the MOSFETs commonly used in mobile - Compliant to JEDEC PUB95 MO-220 computer power supplies. QFN - Quad Flat No Leads - Package Outline - Near Chip Scale Package footprint, which improves The ISL6207 also features a three-state PWM input that, PCB efficiency and has a thinner profile working together with most of Intersil multiphase PWM controllers, will prevent a negative transient on the output Pb-Free Plus Anneal Available (RoHS Compliant) voltage when the output is being shut down. This feature eliminates the Schottky diode, that is usually seen in a Applications microprocessor power system for protecting the Core Voltage Supplies for Intel and AMD Mobile microprocessor, from reversed-output-voltage damage. Microprocessors The ISL6207 has the capacity to efficiently switch power High Frequency Low Profile DC/DC Converters MOSFETs at frequencies up to 2MHz. Each driver is capable of driving a 3000pF load with a 15ns propagation delay and High Current Low Output Voltage DC/DC Converters less than a 10ns transition time. This product implements High Input Voltage DC/DC Converters bootstrapping on the upper gate with an internal bootstrap Schottky diode, reducing implementation cost, complexity, Related Literature and allowing the use of higher performance, cost effective Technical Brief TB363 Guidelines for Handling and N-Channel MOSFETs. Adaptive shoot-through protection is Processing Moisture Sensitive Surface Mount Devices integrated to prevent both MOSFETs from conducting (SMDs) simultaneously.
