S-8352A54MC-K3NT2U

Overview

The S-8352A54MC-K3NT2U is a step-up switching regulator manufactured by ABLIC Inc. It operates with a fixed output voltage of 5.4 V and supports an output current capability defined by its transistor driver configuration. The device utilizes a boost topology with a switching frequency of 100 kHz. It functions within an input voltage range of 900 mV to 10 V and maintains operation across a temperature range of -40°C to +85°C. The component is housed in an SC-74A (SOT-753) surface-mount package.

Feature Summary

• Integrates a step-up function with positive output configuration for voltage boosting applications
• Utilizes a 100 kHz switching frequency to manage power conversion efficiency
• Features a transistor driver output type suitable for specific load driving requirements

Applications

• Battery-powered portable devices requiring voltage elevation
