DESCRIPTION
The FT822 is a current-mode control PFC LED
driver IC. It provides a controlled on-time to regulate
the output and achieve natural power factor
correction. The highly linear multiplier makes the
device capable of working in wide input voltage
range applications (from 85V to 265V) with an
excellent THD.
The device features extremely low consumption (≤
50µA before start-up and ≤ 4mA operating) and
includes a disable function suitable for IC remote
ON/OFF control, which makes it easier to comply
with energy saving norms.
The FT822 features fruitful protections like OTP,
OVP, OSCP. Adjustable output overvoltage
protection(OVP) enables to safely handle overvoltage
resulting from load disconnection. Output Short
Circuit Protection (OSCP) reduces the input power
consumption when Output Short Circuit is detected.
The totem-pole output stage is capable of driving a
MOSFET or IGBT with source and sink currents of
±400mA typically. The device is optimized for low
THD LED lighting application up to 60W.
