MAXIM INTEGRATED PRODUCTS MAX1932ETC+ DC-DC Switching Boost (Step Up) Regulator, Adj., 2.7V-5.5Vin, 4.5V-90V/10mA out, 300 kHz, TQFN-12The MAX1932ETC+ is a digitally controlled, 0. 5% accurate, safest APD bias supply in 12 pin TQFN package. It generates low noise, high voltage output to bias avalanche photodiodes (APDs) in optical receivers.

The MAX1932ETC+ is a digitally controlled, 0.5% accurate, safest APD bias supply in 12 pin TQFN package. It generates low noise, high voltage output to bias avalanche photodiodes (APDs) in optical receivers. Very low output ripple and noise is achieved by a constant frequency PWM boost topology combined with a unique architecture that maintains regulation with an optional RC or LC post filter inside its feedback loop. The output voltage can be accurately set with external resistors, internal 8bit DAC, external DAC or other voltage source. This optimizes utilization of DAC resolution for applications that may require limited output voltage range such as 4.5V to 15V, 4.5V to 45V, 20V to 60V, or 40V to 90V. Protection features provides safe operation, accurate high side current limit, avalanche indicator flag. It is used in optical receivers and modules, fibre optic network equipment, telecom equipment, laser range finders and PIN diode bias supply.
- Input supply voltage range from 2.7V to 5.5V & operating supply current of 1mA at TA = -40°C to 85°C
- Operating temperature range from -40°C to 85°C
- Unique architecture delivers excellent accuracy for improved system performance
- Precision reference and error amplifier maintains 0.5% output voltage accuracy
- Protects expensive APDs against adverse operating conditions while providing optimal bias
- Output voltage flexibility facilitates multiple applications and design approaches
- Output voltage via 8bit SPI compatible
- Small circuit footprint reduces equipment size
- VIN maximum shutdown supply current of 65µA at TA = -40°C to 85°C
- Switching frequency range from 240KHz to 360KHz at TA = -40°C to 85°C

Fun, engaging, and cute toy for dogs!
Color: Yellow - Fish Skewer, Color: Yellow - Fish Skewer
I got the fried fish toy for my dog. So far, he really enjoys the squeaking noise and comes running every time he hears it. The toy material is pretty thick and is holding up well during playtime. The size of this toy is perfect for my small dog but it might be a bit small for larger dogs.
Overall it's a fun and super cute toy for my pets that's become a favorite!

Fun enrichment
Color: Yellow - Fish Skewer, Color: Yellow - Fish Skewer
Bought this to keep my dog busy while I’m out, and surprisingly it works. It’s soft, lightweight, and he was interested right away. Hiding treats inside turns it into a sniffing challenge that keeps him occupied longer than expected.
The squeaker does its job, and the material feels gentle, but this is not for heavy chewers. If your dog destroys toys for sport, proceed with caution.
Overall, it’s a fun enrichment toy that helps with boredom. Great for light to moderate play and dogs who don’t choose violence every day.

Really cute and great for photos
Color: Yellow - Fried Chicken Leg, Color: Yellow - Fried Chicken Leg
This drumstick plush toy is super cute and looks great in pictures. My dog liked it right away and keeps carrying it around.
It’s soft, lightweight, and the size is just right. We’ve already taken a few fun photos with it, and it would also make a nice little gift for someone with a dog.
Simple, well made, and definitely worth it.

Don't Bother Unless You Have Something The Size of a Chihuahua
Color: Yellow - Fried Chicken Leg
Title is definitely deceiving. We have 2 Pitbulls and a Bull Terrier. They simply looked at this thing and it blew into pieces. These are more for smaller dogs. I wouldn't even say medium. It was just a big disappointment. I was excited to give them this toy, until it arrived and I saw how small it was.

Tiny
Color: Yellow - Fried Chicken Leg
Was disappointed. The toy is tiny. I don’t think a puppy could use it. The design was great, except for the size.
