RS2322  
High Accurate non-isolated Buck-Boost  
LED Driver with Active PFC  
DESCRIPTION  
FEATURES  
The RS2322 integrates active power factor correction  
and works in quasi resonance mode in order to reduce  
the MOSFET switching losses. The multi-protection  
features of RS2322 greatly enhance the system reliability  
and safety. The RS2322 features over voltage protection,  
short circuit protection, cycle-by-cycle current limit, VDD  
UVLO and auto-restart over-temperature protection. The  
driver output voltage is clamped at maximal 19V to  
protect the external power MOSFET.  
High efficiency (Reach 90%)  
Active Power Factor Correction (>0.9)  
High precision output current regulation (-3%~+3%)  
when universal AC input voltage (85VAC~265VAC)  
Lowest cost and very less component count solution  
Non-Isolated Buck-Boost application  
Need not transformer to simplify design  
Accurate Constant Current Output  
Quasi Resonance Mode for High Efficiency  
Support no electrolytic capacitor  
The RS2322 is especially designed for non-isolated LED  
driver. The building in perfect current compensation  
function ensures the accurate output current. RS2322  
has very less external components because of high  
integrated and simple topology. Thanks to novel power  
supply, RS2322 need not use transformer and it could  
simplify PCB design.  
Programmable output current setting  
Tight tolerances and negligible temperature  
variation  
Frequency jittering dramatically reduces EMI,  
minimizes EMI filter cost  
Building in current compensation  
Building in 450nS LEB time for CS pin  
Audio noise free operation  
PROTECTION FEATURES  
SOP-8 Pb free package  
VDD 26V over-voltage protection  
Gate 19V clamped voltage  
Building in hysteresis OTP (145)  
Cycle-by-cycle current limiting  
Inductor anti-saturation  
ZCD pin short to GND  
ZCD pin open  
CS pin open  
LED open protection  
LED+ and LED- short protection  
APPLICATIONS  
Cell phone charger  
Small power adaptor  
LED lamp  
Industrial controls
