EZBuck regulator is I2C-controllable

EZBuck regulator is I2C-controllable

Alpha and Omega Semiconductor introduced the EZBuck regulator family with I2C control. The first two, the 4-A AOZ2231CQI-01 and the 8-A AOZ2233CQI-02, provide a compact, efficient power converter solution for next-generation chipsets and FPGAs. Microprocessors and SoCs often use dynamic voltage scaling to reduce power dissipation and improve system performance, which often requires several external components. The 4-A AOZ2231CQI-01 and the 8-A AOZ2233CQI-02 make the design of such converters simple by allowing the system designer to control the output voltage from 0.6 V to 1.79 V using an I2C interface with 9.375-mV steps.

Both the 4-A and the 8-A devices are available in a footprint-compatible QFN 4 x 4-mm package, allowing designers an easy upgrade path as power requirements increase. The devices accept an input voltage range from 6.5 V to 28 V with a built-in 5.3-V regulator, making single-supply operation possible. The proprietary COT architecture provides ultra-fast load transient response performance and allows stable and low-voltage ripple operation with small ceramic capacitors. Competing solutions often need to generate a larger output ripple voltage to stabilize the circuit. Additionally, the input feed-forward feature provides a constant switching frequency over the entire input voltage range, further alleviating noise concerns.

µModule regulator is EN55022 B-compliant

µModule regulator is EN55022 B-compliant

Analog Devices’ Power by Linear LTM4653 is a 58-VIN step-down µModule regulator that can safely operate from unregulated or fluctuating 24-V to 48-V input supplies in noisy environments. Integrating input and output filters enable the device to meet the EN55022 Class B EMC standards, and the low EMI architecture makes it suitable for use in signal processing applications.

The output voltage is adjustable with one resistor from 0.5 V to 94% of VIN, providing the ability to use one product to generate common system bus voltages of 3.3 V, 5 V, 12 V, and 24 V. The LTM4653 houses a switching regulator controller, power switches, inductor, and other supporting components in a 15 x 9 x 5.01-mm BGA package. Only the bulk input and output filter capacitors are needed to complete the design. The LTM4653 operating temperature range is –40°C to 125°C.
