NCP81166A

NCP81166, NCP81166A Synchronous Buck MOSFET Drivers The NCP81166/A is a high performance dual MOSFET gate driver optimized to drive the gates of both high−side and low−side power MOSFETs in a synchronous buck converter. 2mm x 2mm DFN8 package allows for space−optimized board layout. 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. http://onsemi.com 1 DFN8 MN SUFFIX CASE 506CN Features Space−Efficient 2 mm x 2mm DFN8 Thermally−Enhanced Package VCC Range of 4.5 V to 13.2 V Integrated Bootstrap Diode Pre−OVP Function Protects Load during HS FET Short ♦ NCP81166: 2.25 V SW Trip Threshold ♦ NCP81166A: 1.8 V SW Trip Threshold Zero Current Detect Function Provides Power Saving Operation during Light Load Conditions Bi−directional Enable Feature pulls Enable pin low during pre−OVP and UVLO Faults 5 V tri−state PWM Logic Adaptive Anti−Cross−Conduction Circuit Protects against Cross−Conduction during FET turn−on and turn−off Output Disable Control turns off both MOSFETs via Enable pin VCC Undervoltage Lockout Direct interface to ASP1252, ASP1400 and other compatible PWM Controllers These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS ...
