S-8337ACGC-T8T1G

Overview

The S-8337ACGC-T8T1G is a positive output step-up DC-DC controller IC manufactured by ABLIC Inc. It operates within a supply voltage range of 1.8V to 6V and features a switching frequency between 257.4kHz and 1.134MHz. The device utilizes current mode control with a maximum duty cycle of 0.89. It is housed in an 8-TSSOP package (4.40mm wide) and supports operation temperatures from -40°C to 85°C. Key control characteristics include overcurrent protection, enable functionality, and frequency control.

Feature Summary

• Current mode boost regulation for efficient power conversion
• Integrated overcurrent protection and enable pin control
• Adjustable switching frequency capability

Applications

• Portable electronic devices requiring step-up voltage conversion
• Battery-powered systems needing regulated positive output
• General purpose DC-DC power management circuits

Procurement Notes

Verify component status as this part may be marked Not For New Designs. Confirm availability through authorized distributors as stock levels vary. Ensure the 8-TSSOP package matches your PCB footprint requirements. Check RoHS compliance documentation for regulatory adherence. Validate lead times due to potential manufacturing constraints.

Selection Notes

Select this controller when a compact solution for boosting input voltages is required. The 1.8V minimum operating voltage allows compatibility with single-cell lithium batteries. Consider the thermal performance within the specified -40°C to 85°C range. Ensure external components support the adjustable frequency range. Verify that the transistor driver output meets load drive requirements.

Part Context

This component belongs to the S-8337 series of switching controllers designed for portable applications. It complements other PMIC offerings from ABLIC by providing efficient step-up regulation. The series focuses on small form factors and low standby currents suitable for battery-operated equipment.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternative ABLIC S-8337 variants or comparable boost controllers from other manufacturers based on pinout and electrical specifications.
