2 / 16 page 2 SANKEN ELECTRIC CO., LTD. LC5200-DS, Rev. 6.0 Off-Line LED Driver ICs LC5200 Series Electrical Characteristics • The polarity value for current specifies a sink as "+ ," and a source as “−,” referencing the IC. • When pin numbers of the SOP8 differ from those of the DIP8, they are indicated in parentheses for the SOP8. Absolute Maximum Ratings Unless specifically noted, TA is 25°C Characteristic Symbol Notes Pins Rating Unit Main Power Supply Voltage VBB LC5202D LC5202S LC5203D 6 – 8 (7 – 8) 250 V LC5205D LC5205S LC5210D 450 V Output Breakdown Voltage VO LC5202D LC5202S LC5203D 5 – 4 (5,6 – 4) 250 V LC5205D LC5205S LC5210D 450 V Output Current1 IO LC5202D LC5202S LC5205D LC5205S Pulse width ≥ 1 μs 5 – 4 (5,6 – 4) 0.5 A LC5203D LC5210D 1.0 A PWM Pin Voltage2 VPWM 2 – 8 −0.3 to VZ V REF Pin Input Voltage VREF 3 – 8 −0.3 to VREG + 0.3 V SEN Pin Voltage VSEN Pulse width ≥ 1 μs 4 – 8 −0.3 to 4 V Allowable Power Dissipation3,4 PD LC5202S LC5205S Mounted on Sanken evaluation board for the SOP8 – 0.85 W LC5202D LC5203D LC5205D LC5210D Mounted on Sanken evaluation board for the DIP8 – 1.73 W Operating Ambient Temperature TA – −40 to 105 °C Storage Temperature Tstg – −40 to 150 °C Channel Temperature TJ – 150 °C 1 The Output Current rating may be limited by duty cycle, ambient temperature, and heat sinking. Under any set of conditions, do not exceed the specified junction temperature, TJ. 2 VZ here is the breakdown voltage of the Zener diode that is internally connected between the PWM pin and GND: VZ = 6.3 V (typ). Maximum input current is 1 mA. 3 Allowable Power Dissipation, PD, depends on PWB circuit trace layout. 4 Refer to the TA versus PD curve. |
