CHP2630 is a single-channel 10MHz four phase 12A DCDC buck converter.
CHP2635 is a dual-channel dual phase 5A DCDC buck converter.
This IC is designed as a stand-alone component without integrated passives, resulting in the smallest possible footprint.
The Dynamic Voltage Control (DVC) supports adaptive adjustment of the output voltage depending on the load. The DVC can be controlled either via direct register writes through the communication interface (I2C or SPI) or via input pins.
A remote sensing feature is included to provide high accuracy and to support various PCB routing schemes.
Integrated protection features for increased system reliability.
