Product Overview
NCP81062: Synchronous Buck MOSFET Driver
For complete documentation, see the data sheet
Product Description
The NCP81062 is a high-performance MOSFET gate driver in a 3 mm x 3 mm packaged, optimized to drive the gates of both highside and low-side power MOSFETs in a synchronous buck converter. Zero current detect feature allows for a high-efficiency solution
even at light load conditions. Pre-OVP feature aids in protecting the load in the event of a short across the high-side FET. VCC
UVLO ensures the MOSFETs are off when supply voltages are low. A bi-directional Enable pin provides a fault signal to the
controller when a pre-OVP or UVLO fault is detected.
Features
Benefits
• Adaptive Anti-Cross-Conduction
•
•
•
•
• Protects against cross-conduction during FET turn-on and
turn-off
• Minimizes external component count
• Provides power saving operation during light load conditions
• A single signal places the output into a high-impedance state
• Ensures all MOSFETs are in off-state when supply voltages
are low
• Aids in protecting load during HS FET short
• Provides a fault signal to the controller when a preOVP or
UVLO fault is detected
