Function Introduction
GLp640X is a four-way digital isolator with integrated isolation DC/DC. The isolated DC/DC converter can provide a maximum output power of 500mW. The isolated output of the input 5V power supply can achieve a voltage of 5V or 3.3V, and the isolated output of the input 3.3V power supply can achieve a voltage of 3.3V. The whole power supply system is integrated in one chip. In the space-constrained isolation design scheme, this series of chips no longer need to use isolated power supply alone.
The GLp640X isolator can provide four independent isolation channels to encode the data at the input end at high frequency and recover the signal at the output end.
