3 Company Confidential PowerBlox TM vs Controllers and FETs  Customer  “I like your PowerBlox TM 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.”  PowerBlox TM are not priced to compete with discrete solutions  The customer must value those items on the previous page

4 Company Confidential 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

5 Company Confidential The 1K Prices  Higher Current  Higher Price  Higher Frequency  Higher Price

6 Company Confidential Competition – Only LT and Sipex >4A

7 Company Confidential Competition – 1K Pricing vs Value 6A 8A 12A 3A Competition Tough

8 Company Confidential 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

9 Company Confidential 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.

10 Company Confidential PowerBlox TM Roadmap – New Features  Reduced external component  No external compensation  No 3-4 less external components for current limit  Current limit can be used on entire output voltage range  TTL enable pin  PGOOD flag  Available 10/07
