S-8340C50AFT-T2-U

Overview

The S-8340C50AFT-T2-U is a CMOS step-up switching regulator controller manufactured by ABLIC Inc. It operates with an input voltage range of 0.9V to 10V and provides a fixed positive output voltage of 5.0V with 2.0% accuracy. The device features a switching frequency of 250kHz and supports a maximum duty cycle of 85%. It is housed in an 8-TSSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• CMOS step-up switching regulator controller architecture
• Fixed 5.0V output with high precision
• Wide input voltage operating range

Applications

• Battery-powered portable devices requiring voltage boosting
• General purpose DC-DC conversion circuits
• Embedded systems needing stable 5V supply from lower voltage sources

Procurement Notes

Verify the specific suffix T2-U for tape and reel packaging configuration. Confirm the 8-TSSOP package type matches the PCB footprint requirements. Ensure the 250kHz switching frequency aligns with electromagnetic interference constraints in the target design.

Selection Notes

Select this component when a fixed 5.0V boost output is required with minimal external component count. The 2.0% output accuracy suits applications demanding stable reference voltages. Consider the 8-TSSOP package size for space-constrained designs compared to larger packages.

Part Context

This part belongs to the S-8340/8341 series of CMOS step-up switching regulators. It shares architectural similarities with other members like the S-8341 series but differs in specific output voltage settings and package options. The series is designed for efficient power management in compact electronic devices.

Replacement Considerations

The S-8340A56AFT-T2-U is a related variant within the same series, offering different output characteristics. Verify compatibility if substituting with other S-8340 family members, ensuring pinout and electrical specifications match the existing circuit design.
