Dual Channel Synchronous
Rectified Buck MOSFET
Driver
optimized to drive the gates of both the high and low−side Power
MOSFETs in a MultiPhase Synchronous Buck converter. Each of the
drivers is capable of driving a 3000 pF load with only a 12 nS
transition time. Together with a wide 5−12 V MOSFET gate drive
voltage range, adaptive shoot−through protection and reduced
non−overlap time, the NCP6602 allows optimizing applications for
the highest converter efficiency.
external capacitor to reduce parts cost and count, and allows the
use of high−performance cost−effective N−Channel MOSFETs.
Undervoltage Lockout circuitry ensures that both driver outputs are
low when the supply voltage is low, and a Thermal Shutdown function
provides the IC with overtemperature protection.
