LM2662MX Application Field and Working Principle
The LM2662MX is a type of DC-DC switching regulator, which belongs to the project management integrated circuit (PMIC) series of voltage regulators. The LM2662MX is specially designed to be used in simple flyback, buck-boost and forward regulator topologies. It is designed in such a way that it supports several power management functions including over current protection, output voltage programming, thermal protection, soft start and short circuit protection.
Application Field
The LM2662MX is described as “high-efficiency, flexible and low-cost” DC-DC converter. It can support several power management functions including over current protection, output voltage programming, thermal protection, soft start and short circuit protection. It is well-suited for a wide range of applications including mobile communication devices, set-top boxes, digital recorders and many others. It has been designed to offer synchronous and non-synchronous buck, buck-boost and flyback topologies, and is capable of delivering output voltages up to 48V and current up to 1.2A.
Working Principle
The working principle of the LM2662MX is based on the “pulse modulation” technique. It converts the input voltage to the desired level by determining the length of pulses that pass through the switch. The pulses correspond to the sum of the input and output voltages. The duration of each pulse is measured in relation to the on/off time ratio (duty cycle). When the pulse is turned ON, the switch allows the current to pass through, whereby the current is proportional to the level of the input voltage. When the ON duration is limited, the load current is reduced accordingly.
The LM2662MX employs several protections in order to guarantee safety and regulate the output voltage. These protections include output voltage programming protection, over current protection, thermal protection, and short circuit protection. Output voltage programming protection helps to prevent over- and under-voltage operation, while over current protection shuts down the switch before an excessive amount of current flows through it. Thermal protection shuts off the switch and limits the output in case of temperature rise. The LM2662MX is also provided with a soft start feature, which enables continuous operation without large inrush current.
Conclusion
The LM2662MX belongs to the PMIC series of voltage regulators and is described as a “high-efficiency, flexible and low-cost” DC-DC converter. It is capable of delivering output voltages up to 48V and current up to 1.2A and is suitable for a wide range of applications including mobile communication devices, set-top boxes, digital recorders and many others. The working principle of the LM2662MX is based on the “pulse modulation” technique, while several protections are implemented to guarantee safety and regulate the output voltage. These protections include output voltage programming protection, over current protection and thermal protection.
