Intersil Corporation (NASDAQ: ISIL), a leader in innovative power management and precision analog solutions, has recently introduced the ZL2102—a 6A digital synchronous step-down DC/DC power regulator that expands its industry-leading power management IC portfolio. This new device offers an adjustable output voltage range from 0.54V to 5.5V and supports an input voltage range of 4.5V to 14V. The ZL2102 is fully integrated with auto-compensation, making it ideal for complex infrastructure power systems where reliability and performance are critical.
As part of Intersil’s third-generation digital power platform, the ZL2102 features automatic compensation that detects power levels and adjusts accordingly, ensuring stable and reliable operation. This function not only speeds up the design process by eliminating complex calculations 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 continuous load at input voltages between 4.5V and 14V. Its high level of integration includes internal compensation, bootstrap diodes, and a low-dropout regulator (LDO) powered by an internal driver circuit. This allows for a minimal external component count and efficient use of board space, making it an excellent choice for space-constrained designs.
The ZL2102 simplifies the design process from start to finish. It can be configured using external pins or resistors, giving engineers full control over key parameters such as switching frequency, output voltage, soft start ramp/delay, and timing settings. For more advanced configurations, it supports over 70 PMBus commands and integrates seamlessly with Intersil’s PowerNavigator™ GUI, which provides a user-friendly interface for visual timing configuration and drag-and-drop placement—without the need for any coding.
In complex power systems, monitoring and controlling each power rail is essential for ensuring reliability. The ZL2102 integrates these functions, allowing designers to monitor and optimize every aspect of the power supply through the PMBus interface. This eliminates the need for costly hardware changes and makes it easy to scale and replicate designs across different systems.
Industry leaders like CUI, Inc. are increasingly adopting digital power solutions to meet the growing complexity of power requirements. Mark Adams, Senior Vice President of CUI's Novum Advanced Digital Power Division, noted that digital power has become a crucial and reliable option, helping reduce design time, lower risk, and enable engineers to create more efficient and intelligent power systems.
Key Features of the ZL2102:
- Integrated FET 6A converter for reduced size and simplified layout
- External resistor-based configuration for flexible and easy design
- Industry-standard PMBus interface for accurate telemetry monitoring
- Single-Wire DDC Bus for timing, synchronization, and fault management
- On-chip NVM for storing all configuration parameters
- Integrated LDO for +12V single-supply operation
Availability & Pricing:
The ZL2102 6A digital synchronous step-down DC/DC regulator is now available in a 6x36 lead package, priced at $3.10 per unit for 1,000 pieces. Additionally, the ZL2102DEMO1Z evaluation board is available for $80, providing a convenient way to test and develop with the device.
Dimmable Led Grow Lights For Plants
1. Adjustable spectrum: adjustable light LED Grow Light can adjust the wavelength and spectrum of light according to the photosynthesis needs of different plants. Different wavelengths of light have different effects on the growth and flowering of plants, and by adjusting the spectrum, the growth of plants can be maximized.
2. Adjustable light intensity: Adjustable light Grow Light can adjust the light intensity according to the needs of different growth stages of plants. In the early stage of plant growth, it can provide strong light to promote the growth of seedlings; During flowering and fruiting, light intensity can be reduced, saving energy and increasing yields.
3. Adjustable light time: Adjustable light Grow Lights can adjust the light time according to the photoperiod needs of plants. Some plants need long periods of light, while others need shorter periods of light. By adjusting the light time, you can simulate the natural environment and promote the normal growth of plants.
4. Energy saving and environmental protection: The dimmable Growth Light uses LED light source, which has the characteristics of high efficiency and energy saving and long life. Compared with traditional fluorescent lamps or high-pressure sodium lamps, LED light sources are more energy efficient and environmentally friendly, and can provide higher light efficiency.
5. Safe and reliable: dimmable plant lights use low voltage power supply, do not produce heat, will not burn plants. At the same time, it also has over current, over voltage and over temperature protection functions to ensure the safety and reliability during use.
