Imagine the application of LT8602 in therapeutic medical devices [Copy link]

 

In the application of therapeutic medical devices, taking ventilators as an example, the basic power supply voltage is 24V, and the main power supply systems include 24V, 12V, 5V, 3.3V, etc. In this multi-level power supply system, DCDC conversion is required between each level. Due to the existence of high-energy-consuming equipment (fans, etc.), DCDC in parallel at the same level is also required, which makes DCDC devices very large, and LT8602 can solve these problems well.

As a highly integrated power management chip, LT8602 has high application value and effect, especially in therapeutic medical devices. The following is an analysis of the application value and effect of the solution, as well as the advantages and characteristics of LT8602 in therapeutic medical devices.

Typical circuit:

1. Application Value

1. Optimize the power system

In a multi-stage power supply system, the more DCDC converters there are, the more complex the system design will be, and the power consumption and heat will increase. As a flexible power supply system, LT8602 can provide four outputs, reducing the number of DCDC converters, thereby optimizing the power supply system design. In addition, its high efficiency also reduces the power consumption and heat of the system, and improves the stability and reliability of the system.

2. Improve power efficiency

The efficiency of LT8602 is as high as 93%. For high-energy-consuming medical equipment such as ventilators, this high efficiency can greatly reduce energy consumption and improve the energy efficiency ratio of the equipment. It also reduces the heat dissipation requirements of the equipment and simplifies the design process.

3. Simplify circuit design

Since the LT8602 has two high-voltage synchronous buck regulators and two low-voltage synchronous buck regulators, it can meet the power supply requirements of different voltage levels, thus simplifying the circuit design. In addition, its switching frequency can be programmed and synchronized using resistors, making the circuit design more flexible and convenient.

4. Reduce equipment costs

By using a high-performance power management chip such as LT8602, the number of DCDC converters can be reduced, the complexity of circuit design can be reduced, power efficiency can be improved, etc., thereby reducing the cost of the equipment.

2. Application Effect

1. Improve equipment performance

LT8602 has the characteristics of small ripple, which can reduce the impact of power supply ripple on device performance, thereby improving device performance. In addition, its dual-phase clock can reduce input current ripple, further reducing the impact of power supply ripple on device performance.

2. Improve equipment reliability

The reliability of the equipment is improved due to the advantages of LT8602 such as power system optimization, high efficiency and simplified design. In addition, its low ripple burst mode (Burst Mode) with output ripple < 15mV further improves the reliability of the equipment. There are many chips or sensors with high requirements for power supply.

3. Advantages and Features of LT8602

1. Multiple outputs

LT8602 can provide four outputs and has a wide input range, which means it can meet the power supply requirements of different devices and effectively reduce the complexity and cost of the power supply system.

2. High efficiency and high output current

The LT8602 has an efficiency of up to 93%, and can reach an output current of up to 2.5A and 1.5A, which can meet the power supply needs of high-energy-consuming devices. This high efficiency and output current make the LT8602 a very suitable power management chip for therapeutic medical devices.

3. Flexible switching frequency

LT8602 can use resistors to program and synchronize the switching frequency, making circuit design more flexible and convenient. At the same time, its switching frequency range is 250kHz to 2.2MHz, which can meet the switching frequency requirements of different devices.

4. Low ripple burst mode (Burst Mode)

LT8602 has a low ripple burst mode (Burst Mode) with an output ripple of < 15mV. This low ripple burst mode can effectively reduce the impact of power ripple on device performance, thereby improving device performance and reliability. LT8602 uses dual-phase clock technology to reduce input current ripple. The ripple of ordinary LDO is still around 30MV.

5. High integration

LT8602 integrates multiple DC-DC converters, reducing the number of external components and making the power supply design more concise and compact. This high level of integration can reduce the size and cost of the equipment while improving the reliability and stability of the equipment.

6. Programmable output voltage

LT8602 can adjust the output voltage through external resistors, so that the output voltage of the power supply can be flexibly adjusted according to the actual needs of the equipment, thereby meeting the power supply requirements of different equipment. This programmable output voltage function can simplify circuit design and improve the adaptability and flexibility of the equipment.

7. Excellent EMI characteristics

Medical devices have strict requirements for EMC and EMI, and excellent EMI data is essential.

In summary, as a highly integrated power management chip, LT8602 has many advantages and features, such as multiple outputs, high efficiency, flexible switching frequency, low ripple burst mode (Burst Mode), dual-phase clock technology, high integration, and programmable output voltage. In the field of medical equipment, especially therapeutic medical devices, the application value of LT8602 is very high, which can improve the performance, reliability and stability of the equipment, reduce the cost and volume of the equipment, simplify the circuit design, and ensure the safety and security of the equipment. LT8602 is a power management chip that is very suitable for therapeutic medical devices and has broad application prospects and market prospects.
