In an era where energy demand is increasing and system efficiency is paramount, we pursue not only strong functionality, but also efficient and safe products. Xidi Microelectronics Group Co., Ltd., as a leading analog chip manufacturer in China, recently announced the launch of an automotive grade low IQ synchronous boost control chip with spread spectrum function - HL8021. This product meets the strict requirements of industries, telecommunications, and automotive applications with its powerful functions and excellent performance.
1、 Product characteristics
HL8021 is a high-performance boost control chip that can drive synchronous boost N-channel MOSFET power devices and has a wide input voltage operating range of 4.5V to 40V. This design enables it to work stably in various environments, providing continuous and stable power support for application systems. When the bias pin of the controller is connected to the output voltage terminal, the controller can operate at an input power supply as low as 1V after startup, which greatly improves its adaptability in various complex environments.
The switching frequency can be programmed through a resistor on the frequency programming pin, and its constant frequency current control architecture allows the device to synchronize with the external clock on the external synchronization input. This design makes it widely applicable in various environments that require synchronous operations.
In order to optimize light load efficiency, HL8021 also provides three different operating modes - burst mode, pulse jump mode, and continuous inductor current mode. These working modes are selected and controlled through light load mode pin selection, enabling the device to achieve optimal work efficiency under different workloads.
HL8021 has a spread spectrum function to reduce the peak of radiated and conducted EMI noise, making it easier for the system to comply with EMI testing standards. This operating mode is controlled by the spread spectrum function pin. An independent power pin, external power supply can be used to power the internal LDO of VCC. This key function provides a choice to reduce power consumption and improve overall efficiency, further enhancing its working ability in complex electromagnetic environments.
The Xidi Micro HL8021 adopts a 16 pin 3x3mm QFN package, which is very suitable for applications in the automotive, industrial, and telecommunications fields. Its powerful packaging and excellent performance not only facilitate circuit design, but also enable it to perform well in various applications.
2、 Product advantages
2.1. Wide input voltage range: The wide input voltage range of HL8021 ranges from 4.5V to 40V, allowing it to operate stably in various environments. Provide stable work support in both high and low voltage environments.
2.2. Multiple protection measures: In order to ensure the safety and stable operation of the equipment, HL8021 has multiple protection measures. These protective measures can prevent potential problems such as overheating, overcurrent, and overvoltage, thereby ensuring the continuous and stable operation of the equipment.
2.3. High output voltage: The VOUT voltage of HL8021 can be greater than 40V, providing a more stable power supply for the system. This means that it can provide stable power for more devices in high-voltage environments.
2.4. Embedded complex EMI reduction scheme: HL8021 also has an embedded complex EMI reduction scheme, which can help the system easily meet EMI testing standards. This means that it can maintain stable performance in environments with high electromagnetic interference.
3、 Application Prospects
David Nam, General Manager of Xidi Micro, said, "With the automotive level certification of AEC-Q100 Grade 1, powerful ESD protection performance, and wide voltage operating range, the HL8021 can easily meet the extreme challenges of automotive applications." He further pointed out, "In addition, the chip integrates numerous functions to ensure maximum system functional integrity and efficiency
