1 / 8 page LED Lighting IC LC5203D SANKEN ELECTRIC CO.,LTD. 1/8 13 October 2011 ◆Description LC5203D 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. Its high voltage capability allows direct connection to rectified AC supply. Protection features ensure safety LED drive. ◆Package Package: DIP8 ◆Applications LED Lighting equipment LED Light bulb ◆Main Specification MOSFET 250V (MIN), 1.3Ω (MAX) Output Current 1.0A (MAX) Main Supply Voltage 250V (MAX) ◆Features DIP8Package Output MOSFET and controller are included in one package. High voltage supply input Able to direct connection to rectified AC supply. Built-in constant current controller - PWM mode current control circuitry. - Adjustable output current by input voltage to Ref pin. External PWM - PWM signal input to PWM pin enables dimming. - Low signal shuts off output current. Under voltage lockout protection (UVLO) Prevents malfunction when supply voltage is low. Over current protection (OCP) Latched in response to the load short condition. Thermal Shutdown protection (TSD) Protects IC from damage due to excess temperature, auto-restart when temperature drops below threshold Typical application circuit LC5203 VBB OUT Sen GND Reg PWM Ref R1 R2 ROff COff C2 RS LED Di CO L Line Filter Input C1 FUSE http://www.sanken-ele.co.jp |
