ISL6210
FN6392.0
Dual Synchronous Rectified MOSFET
Drivers
The ISL6210 integrates two ISL6208A drivers and is
optimized to drive two independent power channels in a
synchronous-rectified buck converter topology. These
drivers combined with an Intersil ISL62xx multiphase PWM
controller forms a complete single-stage core-voltage
regulator solution with high efficiency performance at high
switching frequency for advanced microprocessors.
The IC is biased by a single low voltage supply (5V),
minimizing driver switching losses in high MOSFET gate
capacitance and high switching frequency applications.
Each driver is capable of driving a 3nF load with less than
10ns rise/fall time. Bootstrapping of the upper gate driver is
implemented via an internal low forward drop diode,
reducing implementation cost, complexity, and allowing the
use of higher performance, cost effective N-Channel
MOSFETs. Adaptive shoot-through protection is integrated
to prevent both MOSFETs from conducting simultaneously.
The ISL6210 features 4A typical sink current for the lower
gate driver, enhancing the lower MOSFET gate hold-down
capability during PHASE node rising edge, preventing power
loss caused by the self turn-on of the lower MOSFET due to
the high dV/dt of the switching node.
The ISL6210 also features an input that recognizes a high-
impedance state, working together with Intersil multiphase
PWM controllers to prevent negative transients on the
controlled output voltage when operation is suspended. This
feature eliminates the need for the schottky diode that may
be utilized in a power system to protect the load from
negative output voltage damage.
