EnerChip EP Solves the Challenges of Energy Harvesting

There are many exciting new applications that could use Energy Harvesting for powering devices. Unfortunately,

utilizing the “free” ambient energy surrounding a system is a complex design challenge, with many questions to

answer including:

• How to interface to energy harvesting transducers?

• How to convert low input power with high efficiency?

• How to manage energy storage?

• How to control power to the rest of the system?

• How to best manage the system power states?

• How to make the entire system “Energy Aware”?

The EnerChip™ Energy Processor solves these challenges by implementing an intelligent integrated approach to

Energy Harvesting Power Management.

Introducing Maximum Peak Power Tracking - the Key to High Efficiency Systems

In order to achieve maximum power transfer from an Energy Harvesting transducer, it is critical to match the

EnerChip Energy Processor CBC915-ACB Pin Designations

The EnerChip EP as the Energy Processing Stage serves to match the impedances of the transducer to the

power converter and decouples the system load from the energy conversion circuits while also controlling the

energy storage elements in the system.
