Summary:The utility model relates to the field of LED direct-current power supply output power control, in particular to an LED power supply output power controllable circuit, which ensures that the LED powersupply output power does not exceed a critical power range under the condition that the load is flexibly increased and the load impedance is reduced, improves the use flexibility of a product, prolongs the service life of the product, and improves the reliability of the product. According to the technical scheme, the circuit with the controllable output power of the LED power source comprises a load circuit unit, a voltage division circuit unit, an integrated operational amplifier circuit unit and a control circuit unit, and the load circuit unit, the integrated operational amplifier circuitunit and the control circuit unit are connected with the voltage division circuit unit. Wherein the load circuit unit and the control circuit unit are respectively connected with the integrated operational amplifier circuit un
