S-8520F20MC-BNFT2U

Overview

The S-8520F20MC-BNFT2U is a CMOS step-down switching regulator controller from the S-8520 series by ABLIC Inc. It operates with a fixed PWM control mode and supports an input voltage range of 2.5 V to 16 V. The device provides a fixed output voltage of 2.0 V and features a typical quiescent current of 100 uA. It functions within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 package.

Feature Summary

Integrates reference voltage source, oscillation circuit, and error amplifier for complete control functionality
Utilizes CMOS process technology to achieve low power consumption during operation
Provides fixed frequency pulse-width modulation (PWM) control for stable regulation

Applications

Battery-powered portable electronic devices requiring efficient step-down conversion
Embedded systems utilizing single-cell lithium-ion or lithium-polymer batteries
Low-power consumer electronics needing compact power management solutions

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental declarations such as REACH registration. Ensure the ordering suffix matches the required package and tape-and-reel specifications for your assembly line requirements.

Selection Notes

Select this controller when a fixed 2.0 V output is required from a 2.5 V to 16 V input source. It is suitable for designs prioritizing low standby current and simple implementation without external feedback resistors. Consider the S-8521 series if programmable switching between PWM and PFM modes is necessary for varying load conditions.

Part Context

This component belongs to the S-8520 series of step-down switching regulator controllers manufactured by ABLIC Inc. The series is designed for applications requiring high efficiency and low current consumption in small form factors. It serves as a core control element in DC-DC converter circuits, managing external power switches to regulate output voltage.
