The TP8005 is a step-down LED constant current driver that operates in the inductor current continuous mode. Used to efficiently drive one or more LEDs in series. The input voltage range of the chip is 5V~36V, and the output current is externally adjustable, up to 1.2A. TP8005 integrates power tube inside, and adopts high-end current detection method. The average current output by the LED can be set through an external resistor, and analog dimming and a wide range of PWM dimming signals can be received through the DIM pin. When the voltage of DIM is lower than 0.3V, the power tube inside the chip is turned off, and the TP8005 enters a low-power standby mode. The TP8005 integrates an automatic temperature compensation control circuit. When the temperature inside the chip exceeds 130°C, the LED output current will gradually decrease with the increase in temperature, and will eventually stabilize at a certain current value. This avoids the LED low frequency flickering problem caused by traditional over-temperature protection. When the temperature inside the chip rises to 150°C, the LED output current decreases to zero ?.
