Synchronous Rectified Buck MOSFET
Drivers
The HIP6601A, HIP6603A and HIP6604 are high frequency,
dual MOSFET drivers specifically designed to drive two
power N-Channel MOSFETs in a synchronous rectified buck
converter topology. These drivers combined with a HIP63xx
or an ISL65xx Multi-Phase Buck PWM controller form a
complete core-voltage regulator solution for advanced
microprocessors.
The HIP6601A drives the lower gate in a synchronous
rectifier to 12V, while the upper gate can be independently
driven over a range from 5V to 12V. The HIP6603A drives
both upper and lower gates over a range of 5V to 12V. This
drive-voltage flexibility provides the advantage of optimizing
applications involving trade-offs between switching losses
and conduction losses. The HIP6604 can be configured as
either a HIP6601A or a HIP6603A.
The output drivers in the HIP6601A, HIP6603A and HIP6604
have the capacity to efficiently switch power MOSFETs at
frequencies up to 2MHz. Each driver is capable of driving a
3000pF load with a 30ns propagation delay and 50ns
transition time. These products implement bootstrapping on
the upper gate with only an external capacitor required. This
reduces implementation complexity and allows the use of
higher performance, cost effective, N-Channel MOSFETs.
Adaptive shoot-through protection is integrated to prevent
both MOSFETs from conducting simultaneously.

HIP6601A, HIP6603A, HIP6604
Functional Pin Description
UGATE (Pin 1), (Pin 16 QFN)
Upper gate drive output. Connect to gate of high-side power
N-Channel MOSFET.
PVCC (Pin 7), (Pin 11 QFN)
For the HIP6601A and the HIP6604, this pin supplies the
upper gate drive bias. Connect this pin from +12V down to
+5V.
For the HIP6603A, this pin supplies both the upper and
lower gate drive bias. Connect this pin to either +12V or +5V.
BOOT (Pin 2), (Pin 2 QFN)
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. A resistor in series with boot
capacitor is required in certain applications to reduce ringing
on the BOOT pin. See the Internal Bootstrap Device section
under DESCRIPTION for guidance in choosing the
appropriate capacitor and resistor values.
PHASE (Pin 8), (Pin 14 QFN)
Connect this pin to the source of the upper MOSFET and the
drain of the lower MOSFET. The PHASE voltage is
monitored for adaptive shoot-through protection. This pin
also provides a return path for the upper gate drive.
Description
Operation
Designed for versatility and speed, the HIP6601A, HIP6603A
and HIP6604 dual MOSFET drivers control both high-side and
low-side N-Channel FETs from one externally provided PWM
signal.
The upper and lower gates are held low until the driver is
initialized. Once the VCC voltage surpasses the VCC Rising
Threshold (See Electrical Specifications), the PWM signal
takes control of gate transitions. A rising edge on PWM
initiates the turn-off of the lower MOSFET (see Timing
Diagram). After a short propagation delay [t
PDLLGATE
], the
lower gate begins to fall. Typical fall times [t
FLGATE
] are
provided in the Electrical Specifications section. Adaptive
shoot-through circuitry monitors the LGATE voltage and
determines the upper gate delay time [t
PDHUGATE
] based
on how quickly the LGATE voltage drops below 2.2V. This
prevents both the lower and upper MOSFETs from
conducting simultaneously or shoot-through. Once this delay
period is complete the upper gate drive begins to rise
[t
RUGATE
] and the upper MOSFET turns on.
PWM (Pin 3), (Pin 3 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.
GND (Pin 4), (Pin 4 QFN)
Bias and reference ground. All signals are referenced to this
node.
PGND (Pin 5 QFN Package Only)
This pin is the power ground return for the lower gate driver.
LGATE (Pin 5), (Pin 7 QFN)
Lower gate drive output. Connect to gate of the low-side
power N-Channel MOSFET.
VCC (Pin 6), (Pin 9 QFN)
Connect this pin to a +12V bias supply. Place a high quality
bypass capacitor from this pin to GND.
LVCC (Pin 10 QFN Package Only)
Lower gate driver supply voltage.
