CN5728
Overview: CN5728 is a current modulation circuit operating at 2.85V to 6V, with a constant output current up to 1.5A. It can be used to drive various light-emitting diodes, including white LEDs. The LED current of CN5728 is set by an external resistor, with a current range of 30mA to 1.5A. The chip integrates a power transistor, greatly reducing the number of external components. The chip also integrates a status register and oscillator circuits. In conjunction with the key input pin and timing capacitor connection pin, CN5728 can control the LED to cycle through three or four states among high light, low light, flash, and off, making it ideal for flashlight applications. Other functions include chip temperature modulation and chip enable input. CN5728 uses an 8-pin SOP8 package with enhanced heat dissipation.
