input must be designed to withstand current transients
equal to the inductor current limit. The input bypass
capacitor reduces the peak currents drawn from the
voltage source, and reduces noise caused by the
MAX8614A/MAX8614B switching action. The input
source impedance determines the size of the capacitor
required at the input. As with the output filter capacitor,
a low-ESR capacitor is recommended. A 22μF, low-ESR
capacitor is adequate for most applications, although
smaller bypass capacitors may also be acceptable with
low-impedance sources or if the source supply is
already well filtered. Bypass AV CC separately from V CC
with a 1.0μF ceramic capacitor placed as close as pos-
For stability, the inverter output filter capacitor, C2,
should satisfy the following:
C2 > (6L V REF I INVMAX ) /
(R CS D- (V REF - V INV ) V INV )
where R CS = 0.0175 (MAX8614B), and 0.040
(MAX8614A). D- is 1 minus the inverter switch duty cycle
and is:
sible to the AV CC and GND pins.
PCB Layout and Routing
Proper PCB layout is essential due to high-current lev-
els and fast-switching waveforms that radiate noise.
Breadboards or protoboards should never be used
when prototyping switching regulators.
