60A Dual Integrated Power Block IRF3546
FEATURES
• Peak efficiency up to 94% at 1.2V
• Two pairs of control and synchronous
MOSFETs in a single PQFN package
• Proprietary package minimizes package
parasitic and simplifies PCB layout
• Input voltage (VIN) range of 4.5V to 21V
• Output current capability of 30A/phase
• Ultra-low Rg MOSFET technology minimizes
switching losses for optimized high frequency
performance
• Synchronous MOSFET with monolithic
integrated Schottky diode reduces dead-time
and diode reverse recovery losses
• Efficient dual side cooling
• Small 6mm x 8 mm x 0.9mm PQFN package
• Lead-free RoHS compliant package
APPLICATIONS
• High frequency, low profile DC-DC converters
• Voltage Regulators for CPUs, GPUs, and DDR
memory arrays
DESCRIPTION
The IRF3546 dual integrated Power Block co-
packages two pairs of high performance control and
synchronous MOSFETs and is ideal for use in high-
density two-phase synchronous buck converters. It is
optimized internally for PCB layout, heat transfer and
package inductance. Coupled with the latest
generation of IR MOSFET technology, the IRF3546
provides higher efficiency at low output voltages
required by cutting edge CPU, GPU and DDR
memory designs.
High switching frequency enables high performance
transient response, allowing miniaturization of output
inductors, as well as input and output capacitors while
maintaining industry leading efficiency. Integrating two
phases in one package while still providing superior
efficiency and thermal performance, the IRF3546
enables smallest size solutions.
The IRF3546 uses IR’s latest generation of low
voltage MOSFET technology characterized by ultra-
low gate resistance (Rg, <0.5Ω) and charge that result
in minimized switching losses. The synchronous
MOSFET optimizes conduction losses and features a
monolithic integrated Schottky to significantly reduce
dead-time and diode conduction and reverse recovery
losses.
The IRF3546 is optimized specifically for CPU core
power delivery in 12V input applications like servers,
certain notebooks, GPU and DDR memory designs.
