ADP3190JRUZ-RL

Special Purpose Regulators Overview

The ADP3190JRUZ-RL is a synchronous buck switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5 V to 28 V and supports output voltages from 0.6 V to 5.5 V. The device features a fixed switching frequency of 300 kHz and delivers up to 1 A of output current. It utilizes a TSSOP-28 package and functions across a temperature range of -40°C to +125°C.

Special Purpose Regulators Feature Summary

• Integrated high-side and low-side drivers for synchronous buck topology
• Fixed 300 kHz switching frequency for optimized passive component size
• Built-in adaptive on-time control for fast transient response

Special Purpose Regulators Applications

• Point-of-load (POL) conversion in industrial equipment
• Voltage regulation for embedded processors and FPGAs
• Power supply stages in telecommunications infrastructure

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'JRUZ' against the manufacturer's official documentation to confirm pinout compatibility and thermal characteristics. Ensure that the operating environment remains within the specified -40°C to +125°C range to maintain performance integrity. Cross-reference the datasheet for any recent product change notices or end-of-life announcements prior to finalizing procurement plans.

Special Purpose Regulators Selection Notes

Select this component when a compact, fixed-frequency solution is required for moderate current applications. The integrated driver capability reduces external component count compared to discrete MOSFET solutions. Consider the 300 kHz frequency trade-off between efficiency and passive component size relative to higher-frequency alternatives.

Special Purpose Regulators Part Context

This part belongs to the ADP3190 series of synchronous buck controllers designed for efficient power management. It complements other Analog Devices PMIC offerings by providing a robust, single-phase solution suitable for space-constrained designs requiring reliable voltage regulation without complex digital control interfaces.

Special Purpose Regulators Replacement Considerations

Consult official substitution guides for direct replacements such as the ADP3190ARUZ-RL or ADP3190BRUZ-RL, ensuring package and electrical parameter alignment.
