PowerBloxTM vs Controllers and FETs
 Customer
 “I like your PowerBloxTM but my controller is $0.60 and the
FETs are $0.30, so my solution is $0.90. I would be willing
to look at your part if the price is the same or lower”
 Sales
 “Sipex’s SP613x series controllers are very competitive
and have some nice features, I could probably help you
cost reduce with these.”
 PowerBloxTM are not priced to compete with
discrete solutions
 The customer must value those items on the
previous page

Where to Sell
 Industrial
 Package could be a barrier
 Medical
 Communication Infrastructure
 Servers
 Embedded systems – good possibilities here
 Package and price are no barrier relative to other
segments

SP765x and SP766x differences
 Over Current Protection (OCP)
SP7650/1/2/3/5 do not have current limit
SP7661/2/3 do have current limit
Current limit is NOT a value driver
SP766x current limit may not be used above 3.3Vout
 Single Supply Operation
SP765x need an external 5V supply to power the internal circuits
SP766x have an internal LDO and can operate from 5V to 22V
 Input Operating Voltage
SP765x can operate to either 20V or 28V
SP766x can operate to 22V
There is no difference in value between 20V and 22V, but 28V may
command a slightly higher value to serve 24VDC applications
 Slightly improved efficiency

SP766x Tricks and Hints
 SP766x current limit function limits Vout to 3.3V,
but if disabled, Vout is not limited
 If current limit is connected and the output is set for 5V, the
part may be damaged.
 The datasheet tells the customer about the 3.3V limitation
on OCP function
 SP766x needs close attention to layout to
prevent highly negative ringing on the switch
node. An app note should be available soon to
address this.
