• Description: Zy2110 10a No-bus Pol
• Manufacturer: Power-One

6.
In this application four POL converters are configured to deliver three independent output voltages. Output
voltages are programmed with the resistors connected between TRIM and MARGIN pins of individual converters.
POL1 is configured as a master (IM pin is grounded) and all other POL converters are synchronized to the
switching frequency of POL1.
All converters are controlled by the common ENABLE signal. Turn-on and turn-off processes of the system are
illustrated by pictures in Figure 5 and Figure 6.
