Multi-function High Brightness LED Driver IC
CN5728
General Description
The CN5728 is a current regulation integrated circuit operating from an input voltage of 2.
85V to 6V, the constant output current can be set up to 1.
5A with an external resistor.
The CN5728 is ideal to be used to drive LED.
The on-chip power
transistor and current sense block greatly reduce the external component count.
The chip also integrates the mode selection circuit, oscillator and state registers, which can control the LED to operate in one of the following four modes: Off, High Brightness(HB), Low Brightness(LB), Flashing and off.
The CN5728 adopts the temperature regulation instead of temperature pr...
