S-8520F25MC-BNKT2U

Overview

The S-8520F25MC-BNKT2U is a step-down DC-DC switching controller from ABLIC Inc., designed for positive output configurations. It operates within an input voltage range of 900 mV to 10 V and provides a fixed 2.5 V output with a maximum output current of 13.2 mA. The device features a switching frequency of 300 kHz and maintains a low quiescent current of 100 uA. It supports operation temperatures from -40°C to +85°C and is housed in a compact SOT-23-5 package.

Feature Summary

• Integrates PWM control for efficient step-down voltage regulation
• Optimized for low power consumption with minimal quiescent current draw
• Supports synchronous rectification for enhanced efficiency

Applications

• Battery-powered portable electronic devices
• Low-power embedded systems requiring stable voltage rails
• Industrial equipment with strict space constraints

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may be restricted. Ensure the specific suffix matches required packaging options such as cut tape or reel formats before finalizing orders.

Selection Notes

Select this controller when a fixed 2.5 V output is required from variable input sources between 0.9 V and 10 V. Consider its 300 kHz frequency for balancing component size and efficiency. Evaluate thermal performance within the -40°C to +85°C range to ensure reliability in target operating environments.

Part Context

This component belongs to the S-8520 series of switching controllers by ABLIC Inc. The series focuses on power management integrated circuits (PMIC) for step-down applications. It shares the SOT-23-5 package form factor with other models in the lineup, facilitating design compatibility across similar power requirements.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other S-8520 variants if pinout and electrical parameters align.
