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. 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 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

cute but not the material I expected
Size: Small, Color: Pure Black
This was really cute, well made and fit as expected. Unfortunately, I have sensitive skin and I found the material to be scratchy so I sent it back.

Nice quality sweater, well made and soft.
Size: Large, Color: Pure Beige
I love this sweater - but I bought it just in time for summer, so it won't get much use until fall! It fits great, it is really soft and the overall quality is quite good. I plan to buy another one in another color as well.

Nice casual looking sweater
Size: Small, Color: Pure Black
I purchased the black/cream inset sweater in a small. I usually wear a small. I fits loose, but NOT baggy. I like the loose fit. The sweater feels so soft. Nice looking sweater. Very happy with the sweater, but could have ordered a medium for a boxier fit.

Good quality & trendy color sweater
Size: Large, Color: Pure Apricot
This sweater is very soft, light and very suitable for keeping mild warm at the temperature of 20c or inside an air conditioning room. Particularly, the trendy color for 2026 in brown suede jacket, this sweater is real good matching item! I like it! 😍😍😍
