Synchronous Buck MOSFET Driver
The NCP81158D is a high- performance dual MOSFET gate driver in a small 3 mm x 3 mm package, optimized to drive the gates of both high- side and low- side power MOSFETs in a synchronous buck converter. The driver outputs can be placed into a high- impedance state via the tri- state PWM and EN inputs. The NCP81158D es packaged with an integrated boost diode to minimize external ponents. A VCC UVLO function guarantees the outputs are low when the supply voltage is low.
Features
- When Device is Powered, Fast PWM Response to EN Going High
- Space- efficient 3 mm x 3 mm DFN8 Thermally- Enhanced Package
- VCC Range of 4.5 V to...
