APPLICATIONS INFORMATION
? Use compact plane for switch node (SW) to improve
cooling of the MOSFETs and to keep EMI down.
? Use planes for V IN and V OUT to maintain good voltage
filtering and to keep power losses low.
? Flood all unused areas on all layers with copper. Flooding
with copper will reduce the temperature rise of power
component. You can connect the copper areas to any
DC net (V IN , V OUT , GND or to any other DC rail in your
system).
When laying out a printed circuit board, without a ground
plane, use the following checklist to ensure proper opera-
tion of the controller.
? Segregate the signal and power grounds. All small
signal components should return to the SGND pin at
one point which is then tied to the PGND pin close to
the source of M2.
? Place M2 as close to the controller as possible, keeping
the PGND, BG and SW traces short.
? Connect the input capacitor(s) C IN close to the pow-
er MOSFETs. This capacitor carries the MOSFET AC
current.
? Keep the high dV/dt SW, BOOST and TG nodes away
from sensitive small-signal nodes.
? Connect the INTV CC decoupling capacitor C VCC closely
to the INTV CC and SGND pins.
? Connect the top driver boost capacitor C B closely to
the BOOST and SW pins.
? Connect the bottom driver decoupling capacitor C DRVCC
closely to the DRV CC and BGRTN pins.
