Intersil Corporation (NASDAQ: ISIL), a leading provider of innovative power management and precision analog solutions, has recently introduced the ZL2102, a 6A digital synchronous step-down DC/DC power regulator. This new addition expands Intersil’s already robust lineup of high-performance power management ICs. The ZL2102 is a fully integrated DC/DC converter that offers auto-compensation, supporting adjustable output voltages ranging from 0.54V to 5.5V. It operates within an input voltage range of 4.5V to 14V, making it ideal for a wide range of applications.
As part of Intersil’s third-generation digital power platform, the ZL2102 features automatic compensation that dynamically adjusts to power levels, ensuring stable and reliable performance. This function not only simplifies design but also enhances system reliability by adapting to component aging over time.
With a compact footprint of just 6mm x 6mm, the ZL2102 delivers up to 6A of continuous load at input voltages between 4.5V and 14V. Its high level of integration includes internal compensation, bootstrap diodes, and an LDO powered by an internal driver circuit, enabling efficient designs with minimal external components and board space.
Designers can configure the ZL2102 using either external pins or resistors, allowing full control over key parameters such as switching frequency, output voltage, soft start settings, and timing configurations. For more advanced users, the device supports over 70 PMBus commands, and when paired with Intersil’s PowerNavigator GUI, it allows for intuitive configuration without the need for coding. The GUI provides visual timing setup and drag-and-drop functionality, significantly speeding up the design process.
In complex power systems, the ZL2102 integrates monitoring and timing control capabilities, allowing designers to manage and optimize every power rail via the PMBus interface. This eliminates the need for costly hardware changes and makes the device easy to integrate and replicate within larger systems.
Industry leaders like CUI, Inc. are increasingly adopting digital power solutions for their efficiency and reliability. Mark Adams, Senior Vice President of CUI’s Novum Advanced Digital Power Division, stated, “As power requirements become more complex, digital power has become a crucial and reliable choice. It helps reduce design time, lower risk, and enables engineers to build efficient and intelligent power systems.â€

The ZL2102 is now available in a 6mm x 36-lead package, priced at $3.10 per unit for 1,000 pieces. Additionally, the ZL2102DEMO1Z evaluation board is available for $80, offering a convenient way to test and implement the device in real-world applications.
High PPFD Plant Growth Light
PPF (luminous flux density) is an indicator used to measure the light energy output of plant lamps, indicating the flow of light energy through a unit area in a unit time. The higher the PPF, the following effects on plant lights:
1. Provide more adequate light energy: high PPF means that plant lamps can output more light energy, which is very important for plant photosynthesis. Photosynthesis is a key process for plant nutrient synthesis and growth, and high PPF can provide more adequate light energy and promote the efficiency of plant photosynthesis, thus promoting plant growth and development.
2. Promote the photosynthesis efficiency of plants: plant lamps with high PPF can provide more intense light, so that the chlorophyll on the leaves of the plants can absorb light energy more fully, thus improving the efficiency of photosynthesis. The improvement of photosynthesis efficiency can increase the nutrient synthesis capacity of plants and promote the growth and development of plants.
3. Increase the yield and quality of plants: high-PPF plant lamps can provide more intense light and promote the growth rate and yield of plants. In agricultural production, the use of high-PPF plant lamps can increase the yield of crops, and the quality of crops may also be improved due to the increase in light intensity.
