Both the LMZM23601 and the LMZM23600 are DC/DC converter modules that are tiny, easy to use, and simple. They are excellent for situations where there is limited space on the circuit board and an efficient power conversion is required. An input voltage range of 4 V to 36 V is supported by both the LMZM23600 and the LMZM23601 devices. Due to the wide voltage range that these modules provide, they can be powered by a wide variety of 5-V, 12-V, or 24-V supplies. Both the LMZM23600 and the LMZM23601 are capable of delivering up to 1 A of current, although the former only supports a load current of up to 0.5 A.
A precision enable circuit, an input UVLO circuit, a built-in soft start, light load mode selection for exceptional power savings or constant frequency operation, current limit protection and power-good flag, are some of the features that are included with the devices. In the device data sheet, you may find additional information on the LMZM23601 and LMZM23600, including the operating range, features, and specs of both devices. Within a range of 2.5 V to 15 V, the output voltage of the adjustable (ADJ) version can be set to the user’s preference.
There are additional fixed output options available for the devices, which include 3.3-V and 5-V outputs. Additionally, for each voltage option, there are two output current choices available: 0.5 A or 1 A. There are two primary evaluation boards: one for the ADJ output voltage possibilities and one for the fixed 5-V and 3.3-V outputs. Both of these outputs are available on both of these evaluation boards. The ADJ output board is available in two different variations: one for devices that can handle currents of up to 1 A, and another that can handle currents of up to 0.5 A. There are also two different output current variants available for the fixed output voltage option boards.
Direct current (DC) can be converted from one voltage level to another with the help of a device called a DC-to-DC converter. This type of converter temporarily stores electrical energy so that it can be converted. In automotive applications, they play a crucial role as an intermediate between systems located throughout the car that operate at different voltage levels.
In the classic 12V electrical architecture, which was prevalent in the automotive industry beginning in the 1950s, control circuitry served as the DC-to-DC converter. This architecture was used extensively until the 1980s. The introduction of emission control features in the 1970s, cruise control in the 1950s, and electrical centers in the 1990s are just some of the new features and innovations that have contributed to an increase in the complexity of vehicle electrical and electronic architectures over the course of several decades. This expansion was made possible by DC-to-DC converters, which took power from the 12V battery and converted it for use in electrical systems operating at lower voltages, such as the instrumentation panel, entertainment system, LED lighting, and sensors (which can require as little as 3.3V). These low-voltage DC-to-DC converters continue to be a vital component of the control circuitry of all automobiles on the road today, including those powered by internal combustion engines as well as those powered by batteries (BEVs).
Because BEVs produce a significantly higher level of electrical power, they call for a DC-to-DC converter that is of a higher quality. Systems with a voltage more than 60V are referred to as high voltage; the voltage range of standard BEV batteries is between 400V and 800V. To provide electricity to an air conditioning unit, the voltage must be reduced to, say, 48V, and further reduced to 12V or lower to provide power to a variety of electronic components located throughout the car. It is also possible that the voltage will need to be increased; for instance, if a battery that operates at 400V is connected to a charging station that operates at 800V, the voltage will need to be increased.
The complexity of the low-voltage design has only been further increased as a result of the proliferation of software-enabled features such as active safety, connection, and entertainment. BEVs are required to have the ability to produce sufficient power to turn the wheels of the vehicle while also being able to step down current to power all of the low-voltage components that make up the software-defined vehicle. In addition to this, they need to have a level of dependability that allows them to fulfill the requirements of the sophisticated driver aid systems and autonomous driving features.
Due to the additional shielding that is required to protect neighbouring components from the electromagnetic interference caused by increased current, high-voltage DC-to-DC converters are significantly larger and heavier than their low-voltage counterparts. The higher current is to blame for this effect. increased power density in DC-to-DC converters, as determined by the kilowatts of electricity per volume, are becoming increasingly popular among the designers of electric vehicles (EVs) because they are trying to reduce the size and weight of the vehicles wherever it is possible to increase their range.
A DC-to-DC converter with power ranging from 700 watts to 4 kilowatts (kW), or even up to 12 kW for a commercial vehicle, is required in order to step down voltage from 400V or 800V to 12V.
The issue is to maximize space use while also preserving the greatest possible standards of both safety and productivity. Some automobile manufacturers have chosen to keep a 12V battery in addition to the main 400V or 800V battery. However, modern designs are attaining higher efficiency by fusing a more complex DC-to-DC converter with a larger battery. This eliminates the need for a separate 12V battery, which reduces the amount of weight, cost, and maintenance that is associated with it.
The efficiency of the DC-to-DC conversion is directly tied to the software that controls the converter, and having a thorough understanding of the vehicle’s overall architecture is necessary for designing both the software and the hardware. Aptiv is drawing on decades of experience on what original equipment manufacturers (OEMs) need to lead the way in vehicle electrification solutions, despite the fact that high-voltage car components are relatively new ground for the industry.
In order to provide the features that original equipment manufacturers and consumers demand, the next generation of software-defined vehicles will need to be compact and efficient. such as over-the-air updates, autonomous driving, cybersecurity, advanced safety, and state-of-the-art user experiences. These functions include: cybersecurity, advanced safety, autonomous driving, and state-of-the-art user experiences.
