Control Design
Generally, telecom power supplies require the
galvanic isolation between a relatively high
input voltage and low output voltages. The most
widely used devices to transfer signals across
the isolation boundary are pulse transformers
and optocouplers.

The MP6001 uses current mode control to
achieve easy compensation and fast transient
response. A type II compensation network
which has two poles and one zero is needed to
stabilize
compensation parameters are provided in the
EV6001DN datasheet.
Boost Controller Application
The MP6001 can be used as a boost controller
as shown in Figure 8.
