FT822 Preliminary

Low THD, High Performance LED Driver

DESCRIPTION

FEATURES

Extremely Low input current THD

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.

Ultra-low (≤50µA) start - up current

Zero-current switching and minimum off time

control

Leading edge blanking instead of RC filtering

Adjustable line compensation

Adjustable Output Overvoltage Protection

(OVP)

VCC Over Voltage Protection

Output Short Circuit Protection(OSCP)

IC Over Temperature Protection(OTP)

Open control loop protection

Disable function

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.

Few external components required

Dip-8/SOP-8 packages

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.

APPLICATIONS

AC/DC LED Driver Applications

Commercial & industrial lighting

Architecture detail lighting

Street lamp lighting

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.
