3.3 Design Tips for Optimized Operation
?
Minimize gate drive current loop - Ground pin of IC, current sense resistor, and
source of power switch should be as close to a single node as practically possible. A
star point connection, although not always practical in real world pcb layout, is
optimum.

?
The IRAC1150-D2 provides a robust 1.5A peak gate current. Optimization of gate
drive resistors is required to achieve optimum performance in terms of system noise,
EMI and efficiency. Match the drive circuit to the power switch and system
requirements – e.g. the larger IRAC1150-300W Demo Board employs an
IRFP27N60K power switch. The turn-on resistance is 8.9 ? and the turn off resistance
is 2.7 ? . This offers a good compromise between switching losses and EMI. The
gate resistors selected will depend upon the desired system level performance, the
power switch selection, the boost diode selection, etc. Please refer to application
notes available on the International Rectifier website which address gate drive design
and optimization.
An additional feature of the IRAC1150-D2 is the OVP/EN function, (pin 5), which is
shown in the circuit of Figure 7 as not connected. This pin can be brought out into
the circuit in order to initiate “sleep mode” feature of the IR1150S control IC.
