NCP81062: Synchronous Buck MOSFET Driver
The NCP81062 is a high-performance MOSFET gate driver in a 3 mm x 3 mm packaged, optimized to drive the gates of both high-side 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- Adaptive Anti-Cross-Conduction
- Integrated bootstrap diode
- Zero Cross Detection
- Output disable turns off both MOSFETs
- Under-Voltage Lockout
- PreOVP
- Bi-directional Enable
- Pb-Free, Halogen/BFR Free and RoHS compliant
| Benefits- 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
