14W Off-line LED Driver, 120VAC, PFC, 14V, 1.0A Load

Focus:

A design based on the HV9931 IC implements a power-factor-corrected, 100-Vac to 135-Vac input, 0-V to 14-V 1-A dc output nonisolated, power supply for driving high-power LEDs. This design requires no electrolytic capacitors, which improves power supply reliability, particularly in high-temperature environments.

What you’ll learn:

• How to build a power-factor-corrected, 120-Vac input, 0-V to 14-V 1-A dc output nonisolated power supply for driving high-power LEDs
