Table 3. Component Suppliers
where:
VRIPPLE is the combined RMS output ripple due to
VRIPPLE,ESR, the ESR ripple, and VRIPPLE,C, the
capacitive ripple. Calculate the ESR ripple and
capacitive ripple as follows:
VRIPPLE,ESR = IRIPPLE x ESR
VRIPPLE,C = IRIPPLE/(2 x
π x 275kHz x COUT)
Layout Recommendations
All connections carrying pulsed currents must be very
short, be as wide as possible, and have a ground plane
as a return path. The inductance of these connections
must be kept to a minimum due to the high di/dt of the
currents in high-frequency switching power converters.
Current loops must be analyzed in any layout pro-
posed, and the internal area kept to a minimum to
reduce radiated EMI. Ground planes must be kept as
intact as possible.
