onsemi FL7701MX Low-Power LED Driver

onsemi FL7701MX Low-Power LED Driver is a simple IC with Power Factor Correction (PFC) function. The special "adopted digital" technique of the IC can automatically detect input voltage condition and send an internal reference signal for achieving a high power factor. The FL7701MX driver automatically enables PFC function when an AC input is applied and automatically disables PFC function when DC input is applied. The FL7701MX Low-Power LED driver comes with built-in HV self-biasing supplying circuit. Typical applications include LED lamp for decorative lighting and low-power lighting.
