High Voltage Synchronous Rectified Buck
MOSFET Driver
The ISL6207 is a high frequency, dual MOSFET driver,
optimized to drive two N-Channel power MOSFETs in a
synchronous-rectified buck converter topology in mobile
computing applications. This driver, combined with an Intersil
Multi-Phase Buck PWM controller, such as ISL6223, ISL6215,
and ISL6216, forms a complete single-stage core-voltage
regulator solution for advanced mobile microprocessors.
The ISL6207 features 4A typical sink current for the lower gate
driver. The 4A typical sink current is capable of holding the
lower MOSFET gate during the Phase node rising edge to
prevent the shoot-through power loss caused by the high dv/dt
of the Phase node. The operation voltage matches the 30V
breakdown voltage of the MOSFETs commonly used in mobile
computer power supplies.
The ISL6207 also features a three-state PWM input that,
working together with most of Intersil multiphase PWM
controllers, will prevent a negative transient on the output
voltage when the output is being shut down. This feature
eliminates the Schottky diode, that is usually seen in a
microprocessor power system for protecting the
microprocessor, from reversed-output-voltage damage.

The ISL6207 has the capacity to efficiently switch power
MOSFETs at frequencies up to 2MHz. Each driver is capable
of driving a 3000pF load with a 15ns propagation delay and
less than a 10ns transition time. This product implements
bootstrapping on the upper gate with an internal bootstrap
Schottky 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.

Functional Pin Description
VCC (Pin 6 for SOIC-8, Pin 5 for QFN)
UGATE (Pin 1 for SOIC-8, Pin 8 for QFN)
Connect the VCC pin to a +5V bias supply. Place a high
quality bypass capacitor from this pin to GND.
The UGATE pin is the upper gate drive output. Connect to
the gate of high-side power N-Channel MOSFET.
BOOT (Pin 2 for SOIC-8, Pin 1 for QFN)
BOOT is the floating bootstrap supply pin for the upper gate
drive. Connect the bootstrap capacitor between this pin and
the PHASE pin. The bootstrap capacitor provides the charge
to turn on the upper MOSFET. See the Bootstrap Diode and
Capacitor section under DESCRIPTION for guidance in
choosing the appropriate capacitor value.
PWM (Pin 3 for SOIC-8, Pin 2 for QFN)
The PWM signal is the control input for the driver. The PWM
signal can enter three distinct states during operation, see the
three-state PWM Input section under DESCRIPTION for further
details. Connect this pin to the PWM output of the controller. In
addition, place a 500kΩ resistor to ground from this pin. This
allows for proper three-state operation under all start-up
conditions.
GND (Pin 4 for SOIC-8, Pin 3 for QFN)
GND is the ground pin. All signals are referenced to this node.
LGATE (Pin 5 for SOIC-8, Pin 4 for QFN)
LGATE is the lower gate drive output. Connect to gate of the
low-side power N-Channel MOSFET.
4
EN (Pin 7 for SOIC-8, Pin 6 for QFN)
EN is the enable input pin. Connect this pin to HIGH to
enable, and LOW to disable, the IC. When disabled, the IC
draws less than 1µA bias current.
PHASE (Pin 8 for SOIC-8, Pin 7 for QFN)
Connect the PHASE pin to the source of the upper MOSFET
and the drain of the lower MOSFET. This pin provides a
return path for the upper gate driver.
Description
Operation
Designed for speed, the ISL6207 dual MOSFET driver
controls both high-side and low-side N-Channel FETs from
one externally provided PWM signal.
A rising edge on PWM initiates the turn-off of the lower
MOSFET (see Timing Diagram). After a short propagation
delay [tPDLLGATE], the lower gate begins to fall. Typical fall
times [tFLGATE] are provided in the Electrical Specifications
section. Adaptive shoot-through circuitry monitors the LGATE
voltage and determines the upper gate delay time
[tPDHUGATE], based on how quickly the LGATE voltage drops
below 1V. This prevents both the lower and upper MOSFETs
from conducting simultaneously, or shoot-through. Once this
delay period is completed, the upper gate drive begins to rise
[tRUGATE], and the upper MOSFET turns on.

FIGURE 1. TIMING DIAGRAM
A falling transition on PWM indicates the turn-off of the upper
MOSFET and the turn-on of the lower MOSFET. A short
propagation delay [tPDLUGATE] is encountered before the
upper gate begins to fall [tFUGATE]. Again, the adaptive shootthrough circuitry determines the lower gate delay time
tPDHLGATE. The upper MOSFET gate-to-source voltage is
monitored, and the lower gate is allowed to rise, after the
upper MOSFET gate-to-source voltage drops below 1V. The
lower gate then rises [tRLGATE], turning on the lower
MOSFET.
This driver is optimized for converters with large step down
ratio, such as those used in a mobile-computer core voltage
regulator. The lower MOSFET is usually sized much larger.
This driver is optimized for converters with large step down
compared to the upper MOSFET because the lower
MOSFET conducts for a much longer time in a switching
period. The lower gate driver is therefore sized much larger
to meet this application requirement. The 0.4Ω on-resistance
and 4A sink current capability enable the lower gate driver to
absorb the current injected to the lower gate through the
drain-to-gate capacitor of the lower MOSFET and prevent a
shoot through caused by the high dv/dt of the phase node.
Three-State PWM Input
A unique feature of the ISL6207 and other Intersil drivers is
the addition of a shutdown window to the PWM input. If the
PWM signal enters and remains within the shutdown window
for a set holdoff time, the output drivers are disabled and
both MOSFET gates are pulled and held low. The shutdown
state is removed when the PWM signal moves outside the
shutdown window. Otherwise, the PWM rising and falling
thresholds outlined in the ELECTRICAL SPECIFICATIONS
determine when the lower and upper gates are enabled.
During start-up, PWM should be in the three-state position
(1/2 VCC). However, with rising VCC, the active tracking
elements for PWM are not active until VCC > 1.2V, which
5
leaves PWM in a high impedance (undetermined) state;
therefore, a 500kΩ resistor must be place from the PWM pin
to GND.
Adaptive Shoot-Through Protection
Both drivers incorporate adaptive shoot-through protection
to prevent upper and lower MOSFETs from conducting
simultaneously and shorting the input supply. This is
accomplished by ensuring the falling gate has turned off one
MOSFET before the other is allowed to turn on.
During turn-off of the lower MOSFET, the LGATE voltage is
monitored until it reaches a 1V threshold, at which time the
UGATE is released to rise. Adaptive shoot-through circuitry
monitors the upper MOSFET gate-to-source voltage during
UGATE turn-off. Once the upper MOSFET gate-to-source
voltage has dropped below a threshold of 1V, the LGATE is
allowed to rise.
Internal Bootstrap Diode
This driver features an internal bootstrap Schottky diode.
Simply adding an external capacitor across the BOOT and
PHASE pins completes the bootstrap circuit.
The bootstrap capacitor must have a maximum voltage
rating above the maximum battery voltage plus 5V. The
bootstrap capacitor can be chosen from the following
equation:
Q GATE
C BOOT ≥ -----------------------∆V BOOT
where QGATE is the amount of gate charge required to fully
charge the gate of the upper MOSFET. The ∆VBOOT term is
defined as the allowable droop in the rail of the upper drive.
As an example, suppose an upper MOSFET has a gate
charge, QGATE , of 25nC at 5V and also assume the droop in
the drive voltage over a PWM cycle is 200mV. One will find
that a bootstrap capacitance of at least 0.125µF is required.

VOLTAGE
Power Dissipation
Package power dissipation is mainly a function of the
switching frequency and total gate charge of the selected
MOSFETs. Calculating the power dissipation in the driver for
a desired application is critical to ensuring safe operation.
Exceeding the maximum allowable power dissipation level
will push the IC beyond the maximum recommended
operating junction temperature of 125°C. The maximum
allowable IC power dissipation for the SO-8 package is
approximately 800mW. When designing the driver into an
application, it is recommended that the following calculation
be performed to ensure safe operation at the desired
frequency for the selected MOSFETs. The power dissipated
by the driver is approximated as:
P = f sw ( 1.5V U Q + V L Q ) + I DDQ V
U
L
CC
where fsw is the switching frequency of the PWM signal. VU
and VL represent the upper and lower gate rail voltage. QU
and QL is the upper and lower gate charge determined by
MOSFET selection and any external capacitance added to
the gate pins. The IDDQ VCC product is the quiescent power
of the driver and is typically negligible.
FIGURE 3. POWER DISSIPATION vs FREQUENCY
Layout Considerations
Reducing Phase Ring
The parasitic inductances of the PCB and the power devices
(both upper and lower FETs) could cause serious ringing,
exceeding absolute maximum rating of the devices. The
negative ringing at the edges of the PHASE node could add
charges to the bootstrap capacitor through the internal
bootstrap diode, in some cases, it could cause over stress
across BOOT and PHASE pins. Therefore, user should do a
careful layout and select proper MOSFETs and drivers. The
D2PAK and DPAK package MOSFETs have high parasitic
lead inductance, which can exacerbate this issue. FET
selection plays an important role in reducing PHASE ring. If
higher inductance FETs must be used, a Schottky diode is
recommended across the lower MOSFET to clamp negative
PHASE ring.
A good layout would help reduce the ringing on the phase
and gate nodes significantly:
• Avoid uses via for decoupling components across BOOT
and PHASE pins and in between VCC and GND pins. The
decoupling loop should be short.
• All power traces (UGATE, PHASE, LGATE, GND, VCC)
should be short and wide, and avoid using via; otherwise,
use two vias for interconnection when possible.
• Keep SOURCE of upper FET and DRAIN of lower FET as
close as thermally possible.
• Keep connection in between SOURCE of lower FET and
power ground wide and short.
• Input capacitors should be placed as close to the DRAIN
of upper FET and SOURCE of lower FETs as thermally
possible.
Note: Refer to Intersil Tech Brief TB447 for more information.

Thermal Management
For maximum thermal performance in high current, high
switching frequency applications, connecting the thermal
pad of the QFN part to the power ground with a via, or
placing a low noise copper plane underneath the SOIC part
is recommended. This heat spreading allows the part to
achieve its full thermal potential.
Suppressing MOSFET Gate Leakage
With VCC at ground potential, UGATE and LGATE are high
impedance. In this state, any stray leakage has the potential
to deliver charge to either gate. If UGATE receives sufficient
charge to bias the device on (Note: Internal circuitry prevents
leakage currents from charging above 1.8V), a low
impedance path will be connected between the MOSFET
drain and PHASE. If the input power supply is present and
active, the system could see potentially damaging currents.
Worst-case leakage currents are on the order of pico-amps;
therefore, a 10kΩ resistor, connected from UGATE to
PHASE, is more than sufficient to bleed off any stray leakage
current. This resistor will not affect the normal performance
of the driver or reduce its efficiency.
