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

charger works, not the adhesive on the ring.
Style: Qi2 Charging Mount
The metal ring adhesive was destroyed by the unit's heat in a few weeks. Do not buy it if you need the adhesive ring to hold the phone. The blinking light ring is annoying - why is it needed.

LOVE this Charger!
Style: Qi2 Charging Mount
This is one of the best chargers I have ever had! My phone stopped charging via the cord and this was my solution and what a awesome one it is! It charges very fast! I also LOVE the way it looks attached to my Tesla screen. Its like having a second screen. I can do Waze on one screen and Tesla navigation on the main screen. I can also control Sirius XM without having to subscribe to it separately for my tesla - which by the way is ridiculous if you already have a subscription…just make sure you done have Allstate DriveWise or other haptics that track weather you’re using your iphone while driving.

It is ok
It is decent. Looks like it would work well. It is a little bulky. I bought this one and another one from a different seller. I returned this one due to the thickness of the arm. It was a little bulky. One thing to be mindful of there is no adjustment for the radius of the arm. Depending on how you position it your phone can be quite far away from the screen, it may not bother you, but for me I wanted them as close as possible
