Abstract

The invention provides a boost switch adjusting circuit, which is connected between a battery and a load, and comprises a control unit, a feedback unit, and an energy storage unit, wherein the control unit comprises a feedback end, a current output end and a pulse output end; the feedback unit is connected with the control unit; the energy storage unit is used for enhancing the output end current at the current output end of the control unit, and comprises a first input end, a second input end and an output end, the first input end of the energy storage unit is connected with the current output end of the control unit, the second input end of the energy storage unit is connected with the pulse output end of the control unit, and the output end of the storage unit is connected with the load and the input end of the feedback unit; and the energy storage unit carries out charging each time when the pulse output end of the control unit outputs a pulse signal and discharges the circuit so as to enhance the current in the circuit. The invention also provides a lamp. The output current can be improved, and the circuit can be applied to a load with higher power.

Description

technical field [0001] The invention relates to a circuit, in particular to a step-up switch regulating circuit and a lamp. Background technique [0002] DC-DC switching regulators are used in a wide range of applications in areas such as portable power management, automotive, industrial, and data communications. A typical step-up DC-DC switching regulator circuit, such as figure 1 As shown, the internal and external inductors of the chip form a switching power supply, and its topology is a step-up BOOST structure. The FB pin is the output feedback pin, which is used to set the output voltage of the circuit and maintain the constant voltage output of the circuit. Since the actual circuit of the step-up switching regulator circuit is generally powered by a battery, the battery voltage is low and continues to drop, and the current value output capability is limited, so that the circuit cannot provide a large enough power when driving a high-power load in practical applicatio...
