Intersil Corporation expanded its family of power management ICs with the new ZL2102, a 6 Amp digital synchronous step-down DC/DC power regulator.

Intersil Corporation expanded its family of power management ICs with the new ZL2102, a 6 Amp digital synchronous step-down DC/DC power regulator. The new ZL2102 is a fully-integrated, auto compensated DC/DC regulator able to support adjustable output voltages of 0.54V to 5.5V operating from input voltages from 4.5V up to 14V. A high level of integration and ease of configurability make the ZL2102 a reliable building block for even the most sophisticated infrastructure power system applications.

The ZL2102 DC/DC regulator is part of Intersil's third generation digital power platform which employs auto compensation, a feature that characterizes the power stage and automatically adjusts accordingly, generating a stable and reliable solution. Auto compensation enables faster design time through the elimination of complex design calculations while providing a highly reliable power supply that can adapt over time to external component aging.

The ZL2102 is a high-performance solution in a small 6mm x 6mm footprint. Integrated synchronous power MOSFETs allow the ZL2102 to deliver continuous loads up to 6A from 4.5V to 14V with high efficiency. With integrated compensation, a bootstrap diode and internal low dropout regulators (LDOs) that provide voltage to the internal gate driver, a complete ZL2102-based design can be created using minimal external components and board space.

The ZL2102 was developed from the ground-up to reduce design time. The ZL2102 can be completely configured with external pin-strap or resistor settings allowing for setup of all key parameters and adjustment of switching frequency, output voltage, soft-start ramp/delay settings and sequencing options. For more advanced setups, the ZL2102 supports over 70 PMBus commands and can be easily configured using Intersil's new PowerNavigator™ GUI. The PowerNavigator GUI enables multiple device design without having to write a single line of code, and its easy-to-use interface with visual sequencing and drag-and-drop placement significantly accelerate design time.

The ZL2102 6A digital synchronous step-down DC/DC regulator is available now in 6 x 6 36-lead QFN packages at $3.10 (USD) each in 1,000-piece units. A demo board, the ZL2102DEMO1Z, is available for a price of $80 (USD) each.
