MAX17497A/MAX17497B
AC-DC and DC-DC Peak Current-Mode Converters
with Integrated Step-Down Regulator
Layout, Grounding, and Bypassing
All connections carrying pulsed currents must be very
short and as wide as possible. The inductance of these
connections must be kept to an absolute minimum due
to the high di/dt of the currents in high-frequency switch-
ing power converters. This implies that the loop areas for
forward and return pulsed currents in various parts of the
circuit should be minimized. Additionally, small-current
loop areas reduce radiated EMI. Similarly, the heatsink
of the main MOSFET presents a dV/dt source; therefore,
the surface area of the MOSFET heatsink should be mini-
mized as much as possible.
Ground planes must be kept as intact as possible. The
ground plane for the power section of the converter
except for a connection at the least noisy section of the
power ground plane, typically the return of the input filter
capacitor. The negative terminal of the filter capacitor,
the ground return of the power switch, and the current-
sensing resistor must be close together. PCB layout also
affects the thermal performance of the design. A number
of thermal vias that connect to a large ground plane
should be provided under the exposed pad of the part for
efficient heat dissipation. For a sample layout that ensures
first-pass success, refer to the MAX17497A evaluation kit
layout available at www.maximintegrated.com .
For universal AC input designs, follow all applicable
safety regulations. Offline power supplies can require UL,
VDE, and other similar agency approvals.
should be kept separate from the analog ground plane,
