LED Lighting IC LC5226D ◆Description LC5226D is non-isolated type driver IC for LED lighting which can achieve high efficiency in simple circuitry. Its compact package which includes output MOSFET and controller, and low external components are suitable for small lighting equipment which requires saving space, like LED light bulb. To meet various requirements, Buck-Boost operation which has wide input/output capability is available. And also, control functions with Ref input are implemented. Its high voltage capability allows direct connection to rectified AC supply. Open protection for Buck-Boost operation and variable OCP improve safeness. 13 October 2011 ◆Package Package: DIP8 ◆Applications  LED Lighting equipment  LED Light bulb ◆Main Specification MOSFET Output Current Main Supply Voltage 450V (MIN), 3.0Ω (MAX) 1.0A (MAX) 450V (MAX) ◆Features  Buck-Boost operation In addition to normal Buck operation, Buck-Boost operation which can both Step-up and down is also available, to operate in wide input/output condition.  Open protection for Buck-Boost operation Protection circuit to prevent damage when load open failure in Buck-Boost operation.  Built-in reference voltage for current setting Precision and easy current setting.  Sleep function Latch off the output by Ref pin input voltage.  Disable function Shut off LED current by Ref pin input voltage.  DIP8 Package Output MOSFET and controller are included in one package.  High voltage supply input  Built-in constant current controller - PWM mode current control circuitry. - Adjustable output current by input voltage to Ref pin.  External PWM Dimming  Variable type over current protection (OCP) - Latch type operation - OCP threshold is adjusted by setting current and temperature to ensure protection.  Under voltage lockout protection (UVLO)  Thermal Shutdown protection (TSD) Typical application circuit Vin FUSE Line Filter AC Input R1 C1 Cin Reg VBB D1 VLED LC5226 Ref PWM OUT GND Sen RS L1 CPWM R2 C2 SANKEN ELECTRIC CO.,LTD. http://www.sanken-ele.co.jp 1 /8 LED LED Lighting IC LC5226D 1 Scope The present specifications shall apply to a LED driver IC for LED lighting, LC5226D. 13 October 2011 2 Outline Type Structure Applications Hybrid Integrated Circuit Plastic Molded (Transfer Mold) LED Lighting 3 Absolute Maximum Ratings (Ta=25℃) Parameter Main Power Supply Voltage Output Breakdown Voltage Output Current PWM Pin Voltage Ref Pin Voltage Sen Pin Voltage Allowable Power Dissipation Junction Temperature Operating Temperature Range Storage Temperature Range ※1 ※2 ※3 ※4 Terminal 6−8 5−4 5−4 2−8 3−8 4−8 ― ― ― Symbol VBB Vo IO VPWM VRef VSen PD Tj Ta Ratings 450 450 1.0 ※1 Units V V A V V V W ℃ ℃ Remarks Exclude Pulse Width
