In the 20-TSSOP (0.173, 4.40mm Width) package, you can find it. Carrying is easy with the Tape & Reel (TR)-shaped packaging. A temperature of -40°C~85°C should be maintained for reliable operation. It should work as long as you use a 2.3V~3.6VV power source. In it, there are 20 terminations. Supply voltages of 2.5V can achieve high efficiencies. PCA9665 numbers are members of this family. There is a clock running on the device at a frequency of 1MHz. There is a supply of 100μA at the moment.
