ADP5310AREZN-R7

Overview

The ADP5310AREZN-R7 is a power management unit integrating dual adjustable buck regulators and a load switch in a 16-lead TSSOP_EP package. It features output currents of 800 mA, 300 mA, and 50 mA with an input voltage range of 2.7 V to 5.5 V. The device operates at switching frequencies up to 3 MHz, achieving low quiescent current of 4 mA. Outputs are adjustable from 0.8 V to the input voltage, supporting lithium-ion and polymer battery applications within a -40°C to +125°C temperature range.

Feature Summary

• Integrates dual synchronous buck converters and a dedicated load switch for space-constrained designs.
• Supports high-frequency operation up to 3 MHz to minimize external component size.
• Provides independent adjustable output voltages starting from 0.8 V.
• Features ultra-low power consumption suitable for battery-powered portable electronics.

Applications

• Portable consumer electronics requiring compact power solutions
• Battery-operated devices utilizing lithium-ion or lithium-polymer cells
• Systems needing multiple regulated voltage rails from a single source

Procurement Notes

Verify the specific suffix 'R7' corresponds to the reel packaging configuration required for your assembly line. Confirm that the 16-TSSOP exposed pad footprint matches your PCB layout guidelines. Ensure compatibility with the 2.7 V to 5.5 V input supply range for your target application environment.

Selection Notes

Select this component when board space is limited due to its integrated dual-buck and load switch architecture. Choose based on the need for high switching frequencies to reduce passive component volume. Verify that the maximum output current requirements of 800 mA and 300 mA align with your system's power budget and thermal constraints.
