Constant Current V/s Constant Voltage LED Driver

What is Current?

Current can be defined as the flow of electric charge from a conductor; this flow measuring unit is ampere (A). Current is of two type, Direct current (DC) flowing in one uniform direction & Alternate Current (AC) changes direction periodically.  

What is Voltage?

Voltage, also known as electric potential difference can be defined as the force driver electric charges through conductors, measured in volts (V). It is similar to the pressure in the circuit, higher voltage provides more energy to move charges. Generated by batteries, generators, or power supplies, voltage is crucial for safe and efficient device operation.

What is the Difference between Constant Current and Constant Voltage?

Basis of Comparison	Constant Current (CC)	Constant Voltage (CV)
Definition	A power supply/driver that delivers a fixed current regardless of load resistance or voltage fluctuations.	A power supply/driver that maintains a fixed output voltage regardless of load current changes.
Input	Requires regulated AC or DC input depending on design.	Requires regulated AC or DC input depending on deign.
Output	Current remains constant; voltage varies with load.	Voltage remains constant; current varies with load.
Application	Commonly used for LEDs, laser diodes, battery charging, and devices sensitive to current fluctuations.	Used in electronics, appliances, communication equipment, and loads requiring stable voltage.
Thermal Handling (THS)	Better for heat-sensitive loads, prevents overheating by limiting current.	May cause overheating in devices like LEDs if current is not controlled.
Power Factor (PF)	Typically higher PF in LED drivers and industrial applications.	PF depends on load and driver design, usually lower in simple CV supplies.
Efficiency	More efficient in applications where current regulation is critical (e.g., LEDs).	Efficient when voltage regulation is primary, such as in DC power supplies.
Load Dependency	Voltage changes depending on load resistance.	Current changes depending on load resistance.
Safety	Protects current-sensitive devices.	Protects voltage-sensitive devices.
