Product Overview
NCP5911: MOSFET Driver, IMVP7.0 Compatible, Synchronous Buck
For complete documentation, see the data sheet
Product Description
NCP5911 is a high performance dual MOSFET driver optimized to drive the gates of both high- and low-side power MOSFETs in a
synchronous buck converter. It can drive up to a 3.0 nF load with a 25 ns propagation delay and 20 ns transition time.
Adaptive anti-cross-conduction and power saving operation circuit can provide a low switching loss and high efficiency solution for
notebook systems.
A high floating top driver design can accommodate VBST voltage as high as 35 V, with transient voltages as high as 35 V.
Bidirectional EN pin can provide a fault signal to controller when the gate driver fault detect under OVP, UVLO occur. Also, an
undervoltage lockout function guarantees the outputs are low when supply voltage is low, and a thermal shutdown function provides
the IC with overtemperature protection.
