NCP5359A
Gate Driver for Notebook
Power Systems
The NCP5359A is a high performance dual MOSFET gate driver
optimized to drive the gates of both highside and lowside power
MOSFETs in a synchronous buck converter. Each of the drivers can
drive up to 3 nF load with a 25 ns propagation delay and 15 ns
transition time.
Adaptive nonoverlap and power saving operation circuit can
provide a low switching loss and high efficiency solution for notebook
and desktop 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.
