RS2335 - PSR and Single Stage PFC Controller for LED Lighting - PTC 数据手册 ( 数据表 )

DESCRIPTION
RS2335 is a single stage, flyback and PFC controller controlling the LED current accurately. It operates in primary-side sensing regulation, so opto-coupler and TL431 could be eliminated.
The converter works in quasi-resonant mode in order to reduce the MOSFET switching losses.

FEATURES
• Primary-side Sensing and Regulation Without
   TL431 and Opto-coupler
• Low start up current, typical 3μA
• UVLO_OFF voltage 16V, and enter UVLO_ON at
   7.5V
• Operation in QR mode to improve efficiency
• OCP voltage 0.5V, primary side current sense
   voltage at 0.3V, reduce conduction loss
• LED open and short protection
• Power factor >0.9
• High output current accuracy
• Input AC voltage compensation
• Build in hysteresis OTP
• VDD OVP and VDD Clamp
• Pb-free SOT23-6L

APPLICATIONS
• Cell phone charger
• Small power adaptor
• LED lamp
• Industrial controls
