RS2332

High-Voltage Start-Up Primary Side LED

Controller with Active PFC

DESCRIPTION

FEATURES

The RS2332 integrates 600V ultra high voltage startup

circuit reduces the total power consumption to provide

a high efficiency solution for lighting applications and it

is a single-power stage, isolated, primary-side-control

offline LED lighting controller that achieves high power

factor in a single SOP-8 package. The proprietary

real-current control method can control the LED

current accurately from the primary side information. It

can significantly simplify the LED lighting system

design by eliminating the secondary side feedback

components and the opto-coupler.



Very less components

Build-in 600V start-up circuit

Real current control without secondary feedback

Accurate constant current output

Active power factor correction (>0.9)

Quasi resonance mode for high efficiency

Under voltage lockout (UVLO)

Programmable input AC voltage compensation

Leading edge blanking on CS/ZCD pin

Available in an SOP-8 package

Protection features

- Building in hysteresis OTP

- VCC over voltage protection

- Clamped Gate output voltage to maximal 18V

- Cycle by cycle current limiting on CS

- Secondary peak current protection on CS pin

- Output short to GND protection

- Output programmable over voltage protection

The RS2332 integrates active power factor correction

and works in quasi resonance mode in order to reduce

the MOSFET switching losses. The multi-protection

features of RS2332 greatly enhance the system

reliability and safety. The RS2332 features over

voltage

protection,

short

circuit

protection,

cycle-by-cycle current limit, VCC UVLO and

auto-restart over-temperature protection. The driver

output voltage is clamped at maximal 18V to protect

the external power MOSFET.

APPLICATIONS



Low Power AC/DC offline SMPS for:

- Solid state lighting

- Industrial and commercial lighting
