2 / 6 page ACE715C High Efficiency 1.2MHz 30V Boost LED Driver VER 1.1 2 Absolute Maximum Ratings Parameter Max IN, EN Pin Voltage -0.3V to 6V SW Pin Voltage -0.3V to 30V All Other Pin Voltage -0.3V to 6V Junction Temperature (TJ) 150°C Ambient Temperature (TA) -40°C to 85°C Power Dissipation SOT23-6 600mW Thermal Resistance (θ JA) 250 °C /W Thermal Resistance (θ JC) 130 °C /W Storage Temperature (Ts) -65°C to 150°C Lead Temperature & Time 260°C, 10Sec Packaging Type SOT-23-6 6 5 4 1 2 3 Pin No. Symbol Description 1 LX Power Switch Output. LX is the drain of the internal MOSFET switch. Connect the power inductor and output rectifier to LX. LX can swing between GND and 30V. 2 GND Ground. 3 FB Feedback Input. The FB voltage is 0.25V. Connect a resistor divider to FB. 4 EN Chip enable, but a PWM signal with various duty cycle can directly sent to EN pin to achieve the backlight dimming. 5 OVP Over Voltage Input. OV measures the output voltage for open circuit protection. Connect OV to the output at the top of the LED string. 6 IN Power Supply. Must be locally bypassed. |
