Synchronous Rectified Buck  
MOSFET Drivers  
Features  
• Drives Two N-Channel MOSFETs  
• Adaptive Shoot-Through Protection  
• Internal Bootstrap Device  
The HIP6601B, HIP6603B and HIP6604B 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 the ISL65xx  
series of Multi-Phase Buck PWM controllers and MOSFETs form  
a complete core-voltage regulator solution for advanced  
microprocessors.  
• Supports High Switching Frequency  
- Fast Output Rise Time  
- Propagation Delay 30ns  
• Small 8 Ld SOIC and EPSOIC and 16 Ld QFN Packages  
• Dual Gate-Drive Voltages for Optimal Efficiency  
• Three-State Input for Output Stage Shutdown  
• Supply Undervoltage Protection  
The HIP6601B 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 HIP6603B 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 HIP6604B  
can be configured as either a HIP6601B or a HIP6603B.  
• QFN Package  
- Compliant to JEDEC PUB95 MO-220 QFN—Quad Flat No  
Leads—Product Outline.  
The output drivers in the HIP6601B, HIP6603B and HIP6604B  
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.  
- Near Chip-Scale Package Footprint; Improves PCB  
Efficiency and Thinner in Profile.  
• Pb-Free (RoHS Compliant)  
Applications  
• Core Voltage Supplies for Intel Pentium® III, AMD® Athlon™  
Microprocessors  
• High Frequency Low Profile DC/DC Converters  
• High Current Low Voltage DC/DC Converters

Lower gate driver supply voltage.  
Functional Pin Description  
PVCC (Pin 7), (Pin 11 QFN)  
UGATE (Pin 1), (Pin 16 QFN)  
For the HIP6601B and the HIP6604B, this pin supplies the upper gate  
drive bias. Connect this pin from +12V down to +5V.  
Upper gate drive output. Connect to gate of high-side power N-  
Channel MOSFET.  
For the HIP6603B, 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 a  
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  
“Internal Bootstrap Device” on page 7 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  
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” on page 7 for further details. Connect this pin to the  
PWM output of the controller.  
Operation  
Designed for versatility and speed, the HIP6601B, HIP6603B and  
HIP6604B dual MOSFET drivers control both high-side and low-  
side N-Channel FETs from one externally provided PWM signal.  
GND (Pin 4), (Pin 4 QFN)  
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” on page 4), the PWM  
signal takes control of gate transitions. A rising edge on PWM  
initiates the turn-off of the lower MOSFET (see “Timing Diagram”  
Bias and reference ground. All signals are referenced to this  
node.

Three-State PWM Input  
A unique feature of the HIP660X 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.  
As an example, suppose a HUF76139 is chosen as the upper  
MOSFET. The gate charge, Q  
, from the data sheet is 65nC  
GATE  
for a 10V upper gate drive. We will assume a 200mV droop in  
drive voltage over the PWM cycle. We find that a bootstrap  
capacitance of at least 0.325μF is required. The next larger  
standard value capacitance is 0.33μF.  
In applications which require down conversion from +12V or  
higher and PVCC is connected to a +12V source, a boot resistor in  
series with the boot capacitor is required. The increased power  
density of these designs tend to lead to increased ringing on the  
BOOT and PHASE nodes, due to faster switching of larger  
currents across given circuit parasitic elements. The addition of the  
boot resistor allows for tuning of the circuit until the peak ringing  
on BOOT is below 29V from BOOT to GND and 17V from BOOT  
to VCC. A boot resistor value of 5Ω typically meets this criteria.  
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 rise.  
During turn-off of the lower MOSFET, the LGATE voltage is  
monitored until it reaches a 2.2V threshold, at which time the  
UGATE is released to rise. Adaptive shoot-through circuitry  
monitors the PHASE voltage during UGATE turn-off. Once  
PHASE has dropped below a threshold of 0.5V, the LGATE is  
allowed to rise. PHASE continues to be monitored during the  
lower gate rise time. If PHASE has not dropped below 0.5V within  
250ns, LGATE is taken high to keep the bootstrap capacitor  
charged. If the PHASE voltage exceeds the 0.5V threshold during  
this period and remains high for longer than 2μs, the LGATE  
transitions low. Both upper and lower gates are then held low until  
the next rising edge of the PWM signal.  
In some applications, a well tuned boot resistor reduces the ringing  
on the BOOT pin, but the PHASE to GND peak ringing exceeds  
17V. A gate resistor placed in the UGATE trace between the  
controller and upper MOSFET gate is recommended to reduce the  
ringing on the PHASE node by slowing down the upper MOSFET  
turn-on. A gate resistor value between 2Ω to 10Ω typically reduces  
the PHASE to GND peak ringing below 17V.  
Gate Drive Voltage Versatility  
The HIP6601B and HIP6603B provide the user total flexibility in  
choosing the gate drive voltage. The HIP6601B lower gate drive is  
fixed to VCC [+12V], but the upper drive rail can range from 12V  
down to 5V depending on what voltage is applied to PVCC. The  
HIP6603B ties the upper and lower drive rails together. Simply  
applying a voltage from 5V up to 12V on PVCC will set both  
driver rail voltages.  
Power-On Reset (POR) Function  
During initial start-up, the VCC voltage rise is monitored and gate  
drives are held low until a typical VCC rising threshold of 9.95V is  
reached. Once the rising VCC threshold is exceeded, the PWM  
input signal takes control of the gate drives. If VCC drops below a  
typical VCC falling threshold of 7.6V during operation, then both  
gate drives are again held low. This condition persists until the  
VCC voltage exceeds the VCC rising threshold.  
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 SO8 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  
Internal Bootstrap Device  
The HIP6601B, HIP6603B, and HIP6604B drivers all feature an  
internal bootstrap device. Simply adding an external capacitor  
across the BOOT and PHASE pins completes the bootstrap circuit.

The power dissipation approximation is a result of power  
transferred to and from the upper and lower gates. But, the internal  
bootstrap device also dissipates power on-chip during the refresh  
cycle. Expressing this power in terms of the upper MOSFET total  
gate charge is explained below.

The bootstrap device conducts when the lower MOSFET or its  
body diode conducts and pulls the PHASE node toward GND.  
While the bootstrap device conducts, a current path is formed that  
refreshes the bootstrap capacitor. Since the upper gate is driving a  
MOSFET, the charge removed from the bootstrap capacitor is  
equivalent to the total gate charge of the MOSFET. Therefore, the  
refresh power required by the bootstrap capacitor is equivalent to  
the power used to charge the gate capacitance of the MOSFET.

The 1.05 factor is a correction factor derived from the following  
characterization. The base circuit for characterizing the drivers for  
different loading profiles and frequencies is provided. C and C  
are the upper and lower gate load capacitors. Decoupling capacitors  
[0.15μF] are added to the PVCC and VCC pins. The bootstrap  
capacitor value is 0.01μF.

Figure 2 shows the dissipation in the driver with 3nF loading on  
both gates and each individually. Note the higher upper gate power  
dissipation which is due to the bootstrap device refresh cycle.  
Again PVCC and VCC are tied together and to a +12V supply.  
FIGURE 2. 3nF LOADING PROFILE  
The impact of loading on power dissipation is shown in  
Figure 3. Frequency is held constant while the gate capacitors are  
varied from 1nF to 5nF. VCC and PVCC are tied together and to a  
+12V supply. Figures 4, 5 and 6 show the same characterization for  
the HIP6603B with a +5V supply on PVCC and VCC tied to a +12V  
supply.  
Since both upper and lower gate capacitance can vary,  
Figure 8 shows dissipation curves versus lower gate capacitance with  
upper gate capacitance held constant at three different values. These  
curves apply only to the HIP6601B due to power supply  
configuration.
