S-8355Q15BD-OWA-TFG

Overview

The S-8355Q15BD-OWA-TFG is a step-up DC-DC converter IC from ABLIC, designed for efficient voltage boosting in compact applications. It features a super-small 6-SNB (1.8x2.0 mm) package and operates with a fixed switching frequency of 600 kHz. The device supports PWM control or switchable PWM/PFM modes to optimize efficiency across varying load conditions. It is engineered for high reliability and low power consumption, making it suitable for battery-powered portable electronics where space constraints are critical.

Feature Summary

• Compact 6-SNB package design for space-constrained PCB layouts
• Switchable PWM/PFM control modes for optimized efficiency
• Fixed 600 kHz switching frequency for reduced external component size
• High reliability construction suitable for portable electronic devices

Applications

• Battery-powered portable consumer electronics
• Mobile communication devices requiring voltage boosting

Procurement Notes

Verify the specific suffix OWA-TFG against the official ABLIC datasheet to confirm pinout and electrical characteristics. Ensure compatibility with your PCB footprint, as the 6-SNB package requires precise layout considerations. Check current availability status through authorized distributors, as supply levels may fluctuate. Confirm RoHS compliance documentation if required for your manufacturing standards.

Selection Notes

Select this component when a small form factor is prioritized alongside efficient step-up conversion. The 600 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the switchable control mode if your application demands high efficiency at both light and heavy loads. Ensure the input voltage range matches your power source before finalizing the design.

Part Context

This part belongs to the S-8355 series of step-up converters from ABLIC Inc., known for integrating high-performance power management in minimal footprints. The series targets modern portable devices where battery life and physical size are key design drivers. The Q15BD variant specifically denotes the output voltage setting and package type within this family.

Replacement Considerations

Direct substitutes must match the 6-SNB package and 600 kHz operation. Verify equivalent boost topology and output voltage settings. Cross-reference pinouts carefully, as package variations within the same series may differ. Consult ABLIC's official replacement guide for validated alternatives.
