ADP3153ARU-REEL7

Overview

The ADP3153ARU-REEL7 is a switching controller manufactured by Analog Devices Inc., designed for power supply applications. It operates within a maximum switching frequency of 250 kHz and utilizes current-mode control with constant off-time technology. The device is housed in a TSSOP-20 package, featuring 20 terminals and a plastic/epoxy body. It supports a nominal input voltage of 5 V and functions as a single-channel regulator or controller. The component is rated for operation up to a maximum temperature of 70 °C.

Feature Summary

• Implements current-mode control architecture for precise regulation
• Utilizes constant off-time technology for stable switching performance
• Designed as a dedicated switching regulator or controller IC

Applications

• Switching power supply designs requiring current-mode control
• Industrial power management systems
• General-purpose DC-DC converter controllers

Procurement Notes

Verify the specific suffix ARU against official Analog Devices documentation to confirm the TSSOP-20 package variant. Ensure the application environment remains within the specified 70 °C maximum operating temperature limit. Cross-reference the part number with the manufacturer's latest datasheet to confirm compliance with RoHS standards and availability status, as distribution channels may vary.

Selection Notes

Select this component when a current-mode controlled switching solution with a 250 kHz frequency limit is required. The TSSOP-20 package suits space-constrained PCB layouts. Confirm that the system input voltage aligns with the 5 V nominal specification. Evaluate thermal constraints carefully, as the commercial grade rating limits operation to 70 °C, which may necessitate derating or additional cooling in high-ambient environments.

Part Context

This part belongs to the Analog Devices power management portfolio, specifically focusing on switching regulators. It complements other interface and isolation products from the manufacturer. The ADP series typically addresses power conversion needs in industrial and consumer electronics, providing reliable control for voltage regulation tasks within defined electrical parameters.
