H7310 is a linear high-current high-precision LED driver chip with a withstand voltage of 85V. The output current is adjustable. It only needs an external CS resistor to form a complete constant current drive circuit.
RCS resistance adjusts the output range of 16-1500MA. The voltage difference between the LED port and GND should be determined according to the output current and package power consumption, and it depends on the heat dissipation condition. The voltage difference should not be too large.
H7310 uses a low dropout drive circuit.
H7310 has built-in over-temperature protection, when the temperature reaches 130℃, the output current is reduced.
The H7310 peripheral can be extended for constant current applications, and the output current is reduced when the input voltage is high. The PWM application can also be expanded.
H7310 is packaged in ESOP-8, and the bottom heat sink is connected to the LED port by default.
