Hello All,
I have designed Series Parallel Charge Pump that is used in Power Management circuit to charge the battery.
Details:
It has variable input from < 1V
Output voltage must be > 1.8V
Question:
I don't have load current fixed(assuming must be around 500uA). How do I calculate the power efficiency?
1. Do I fix a constant VOLTAGE source at the output of CP as load and check for input and output current
2. Do I fix a constant CURRENT source at the output of CP as load and check if output voltage reaches 1.8V
Kindly help me understand the methodology to check the power efficiency of Charge Pump
