Absolute Maximum Ratings ● Unless otherwise specified TA = 25 °C, the LO pin is reference voltage level. Parameter Symbol Rating Units Notes DC input voltage VIN 35 V LED pin voltage VLED VIN V FB pin voltage VFB 5 V Allowable Power Dissipation PD 1.3 W Reference layout pattern mounting on the FR4 double-sided PCB. Refer to Section 12.2.2. Junction Temperature Tj − 40 to 125 °C Storage Temperature Tstg − 40to 80 °C * When the junction temperature of the IC becomes 110 °C (min.) or more, the thermal shutdown (TSD) activates. 2. Recommended Operating Conditions ● Unless otherwise specified TA = 25 °C, the LO pin is reference voltage level. Parameter Symbol Min. Max. Units Notes IN-LO Voltage VIN 2.4 * V Output Current ILED 15 150* mA Operating Ambient Temperature TOP − 20 + 80 °C * Since the between VIN and ILED has following relationship, the value of VIN is different by condition. Allowable power dissipation, PD is calculated by Figure 5-1. PD(MAX) = (VIN − VLED) × ILED(MAX) (1) 3. Electrical Characteristics ● Unless otherwise specified TA = 25 °C, the LO pin is reference voltage level. Parameter Symbol Conditions Min. Typ. Max. Units Reference Voltage VFB VIN = 4 V, ILED = 15 mA 0.194 0.200 0.206 V Reference Voltage Temperature Coefficient (1) ΔVFB/TA Tj = 25 °C to 100 °C -0.02 mV/°C Voltage Difference between Input and Output (2) ΔVDIF ILED ≤ 50 mA 0.18 V ILED ≤ 150 mA 0.35 V Overcurrent protection threshold Current IS1 VIN = 4V, VLED = 90 % 160 mA Thermal Shutdown Temperature(1) TSD 110 130 °C (1) Design assurance. (2) The saturation voltage between the IN pin and the LED pin. 4. Thermal Resistance ● Unless otherwise specified TA = 25 °C, the LO pin is reference voltage level. Parameter Symbol Rating Units Notes Junction to Ambient Thermal Resistance θj-A 65 °C/W Junction to Case Thermal Resistance θj-TOP 27 °C/W Marking surface |
