High-Speed, Dual-Phase Driver
with Integrated Boost Diodes
General Description
The MAX8811 2-phase gate driver controls power
MOSFETs in multiphase synchronous step-down con-
verter applications, providing up to 30A output current
per phase. The MAX8811 and MAX8810A (multiphase
power-supply controller) combine to provide an efficient,
low-cost solution for a wide range of multiphase power-
supply applications. The MAX8811 handles system input
voltages up to 26V. Each MOSFET driver is capable of
driving 3000pF capacitive loads with 11ns typical rise
and fall times.
Adaptive shoot-through protection circuitry is imple-
mented to prevent shoot-through currents for the “high-
side off to low-side on ” transition. A programmable
delay is provided for the “low-side off to high-side on”
transition. This maximizes overall converter efficiency
while supporting operation with a variety of MOSFETs.
The MAX8811 provides an easy upgrade path from the
MAX8523 dual driver. Integrated bootstrap diodes
reduce external component count, while an enable
input provides flexibility for power sequencing. The
MAX8811 is available in a space-saving, 16-pin QSOP.
