Description
POWER INTEGRATIONS DPA424PN Flyback Switching Regulator, Fixed, 16V-75V In, DIP-8The DPA424PN is a highly integrated solution DPA Switch Converter IC for DC to DC conversion applications with 16 to 75VDC input. DPA switch uses the same proven topology as TOPSwitch integrating a power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. High performance features are enabled with three user configurable pins and it eliminates up to 50 external components saves space. Hysteretic thermal shutdown
The DPA424PN is a highly integrated solution DPA-Switch Converter IC for DC-to-DC conversion applications with 16 to 75VDC input. DPA-switch uses the same proven topology as TOPSwitch� integrating a power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. High performance features are enabled with three user configurable pins and it eliminates up to 50 external components saves space. Hysteretic thermal shutdown is also provided. In addition, all critical parameters have tight temperature and absolute tolerance.
- Eliminates all external current sensing circuitry
- Built-in auto-restart for output overload/open loop protection
- Externally programmable current limit
- Source connected tab reduces EMI
- Line under-voltage (UV) detection - Meets ETSI standards
- Line over-voltage (OV) shutdown protection
- UV/OV limits gate drive voltage for synchronous rectification
- Fully integrated soft-start for minimum stress/over-shoot
- Supports forward or flyback topology
- Cycle skipping - Regulation to zero load without pre-load

Junk
Just pay for the better ones, these are cheap junk. They can’t even be torn off without falling apart.

Nice bed
Color: Blue, Size: Large (Pack of 1)
Good quality dog bed. My pittie loves to burrow himself under blankets so I figured we would give this a try. He hasn’t figured it out yet but it’s his new favorite spot to take a nap when he’s not on our lap. Love the color and seems to be nicely made. I do wish it came in a bigger size but it’s still big enough for him.

Nice quality bed
Color: Blue, Size: Large (Pack of 1)
Nice quality. My dog loves laying on this bed but hasn’t yet figured out getting inside. I cover him after he lays and he seems to enjoy it

Cozy Bed, Just Needs Fluffing
Color: Blue, Size: Large (Pack of 1)
Our dog took to this bed pretty quickly and seems to like curling up under the cave cover. It’s soft, roomy, and gives that little tucked-in feeling a lot of pets seem to love. The cover doesn’t always stay perfectly shaped, so I have to fluff it back up now and then. Other than that, it looks nice in the corner and seems comfortable enough for daily naps. Solid bed overall, especially for the price.
