S-8352A50MC-K3JT2G

Overview

The S-8352A50MC-K3JT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 900 mV to 10 V and provides a fixed output voltage of 5.0 V. The device utilizes a PWM control scheme with a switching frequency of 110 kHz. It features a low quiescent current of 31 uA and supports a maximum output current of 231 mA. The component is housed in a 5-pin SOT-23 package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency step-up topology optimized for battery-powered applications
• Maintains stable regulation through internal PWM control circuitry
• Designed for minimal power consumption during active operation

Applications

• Portable electronic devices requiring voltage boosting from single-cell sources
• Battery-operated instrumentation systems

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected variant matches the required output voltage tolerance and packaging type for your assembly process. Cross-reference the manufacturer's latest datasheet to validate environmental compliance and operational limits before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 5.0 V boost output is required from inputs as low as 900 mV. The 110 kHz switching frequency allows for compact external passive selection. Consider the 31 uA quiescent current for standby efficiency requirements. Verify that the SOT-23-5 package fits the available PCB real estate and thermal management strategy for the target application environment.
