FEATURES  
DESCRIPTION

•
•
•
•
Drives Two N-Channel MOSFETs with 14-ns  
Adaptive Dead Time  
The TPS28225 and TPS28226 are high-speed  
drivers for N-channel complimentary driven power  
MOSFETs with adaptive dead-time control. These  
drivers are optimized for use in variety of high-current  
one and multi-phase dc-to-dc converters. The  
Wide Gate Drive Voltage: 4.5 V Up to 8.8 V  
With Best Efficiency at 7 V to 8 V  
Wide Power System Train Input Voltage: 3 V  
Up to 27 V  
TPS28225/6 is  
a solution that provides highly  
Wide Input PWM Signals: 2.0 V up to 13.2-V  
Amplitude  
efficient, small size low EMI emmissions.  
The performance is achieved by up to 8.8-V gate  
drive voltage, 14-ns adaptive dead-time control, 14-ns  
propagation delays and high-current 2-A source and  
4-A sink drive capability. The 0.4-Ω impedance for  
the lower gate driver holds the gate of power  
MOSFET below its threshold and ensures no  
shoot-through current at high dV/dt phase node  
transitions. The bootstrap capacitor charged by an  
internal diode allows use of N-channel MOSFETs in  
half-bridge configuration.  
Capable Drive MOSFETs with ≥40-A Current  
per Phase  
High Frequency Operation: 14-ns Propagation  
Delay and 10-ns Rise/Fall Time Allow FSW - 2  
MHz  
•
•
Capable Propagate <30-ns Input PWM Pulses  
Low-Side Driver Sink On-Resistance (0.4 Ω)  
Prevents dV/dT Related Shoot-Through  
Current  
The TPS28225/6 features a 3-state PWM input  
compatible with all multi-phase controllers employing  
3-state output feature. As long as the input stays  
within 3-state window for the 250-ns hold-off time, the  
driver switches both outputs low. This shutdown  
mode prevents  
output-voltage.  
•
•
3-State PWM Input for Power Stage Shutdown  
Space Saving Enable (input) and Power Good  
(output) Signals on Same Pin  
•
•
•
•
Thermal Shutdown  
UVLO Protection  
a
load from the reversed-  
Internal Bootstrap Diode  
The other features include under voltage lockout,  
thermal shutdown and two-way enable/power good  
signal. Systems without 3-state featured controllers  
can use enable/power good input/output to hold both  
outputs low during shutting down.  
Economical SOIC-8 and Thermally Enhanced  
3-mm x 3-mm DFN-8 Packages  
•
High Performance Replacement for Popular  
3-State Input Drivers  
The TPS28225/6 is offered in an economical SOIC-8  
and thermally enhanced low-size Dual Flat No-Lead  
(DFN-8) packages. The driver is specified in the  
extended temperature range of –40°C to 125°C with  
the absolute maximum junction temperature 150°C.  
The TPS28226 operates in the same manner as the  
TPS28225/6 other than the input under voltage lock  
out. Unless otherwise stated all references to the  
TPS28225 apply to the TPS28226 also.  
APPLICATIONS  
•
Multi-Phase DC-to-DC Converters with Analog  
or Digital Control  
•
•
•
Desktop and Server VRMs and EVRDs  
Portable/Notebook Regulators  
Synchronous Rectification for Isolated Power  
Supplies
