In this application four POL converters are configured to deliver three independent output voltages. POL1 and
POL2 are connected in parallel for increased output current. Output voltages are programmed with the resistors
connected between TRIM and VREF pins of individual converters.
POL1 is configured as a master (IM and INTL0…INTL4 pins are grounded) and all other POL converters are
synchronized to the switching frequency of POL1. Interleave is programmed with pins INTL0…INTL4 to ensure
the lowest input and output noise. POL2 has 180° phase shift, POL 3 and POL4 have phase shifts of 270° and
90° respectively.
All converters are controlled by the common ENABLE signal. Turn-on and turn-off processes of the system are
illustrated by pictures in Figure 8 and Figure 9.
