Master-Slave Configurations
The MAX1566/MAX1567 support MAX1801 slave PWM
controllers that obtain input power, a voltage reference,
and an oscillator signal directly from the MAX1566/
MAX1567 master. The master-slave configuration allows
channels to be easily added and minimizes system cost
by eliminating redundant circuitry. The slaves also con-
trol the harmonic content of noise because their operat-
ing frequency is synchronized to that of the MAX1566/
Figure 9. +15V and -7.5V CCD Bias with Transformer
MAX1567 master converter. A MAX1801 connection to
the MAX1566/MAX1567 is shown in Figure 14.
Status Outputs ( SDOK , AUX1OK , SCF)
The MAX1566/MAX1567 include three versatile status
outputs that can provide information to the system. All
are open-drain outputs and can directly drive MOSFET
switches to facilitate sequencing, disconnect loads
during overloads, or perform other hardware-based
functions.
