S1F81150F0A2000

Overview

The S1F81150F0A2000 is a Power Management IC (PMIC) manufactured by Epson Electronics America Inc. It integrates six output voltage regulators, comprising five step-down (buck) converters and one low-dropout (LDO) linear regulator. The component is designed for surface-mount assembly in a 48-QFP package with dimensions of 7x7 mm. This integrated solution allows for efficient power distribution in complex electronic systems requiring multiple regulated voltage rails from a single device.

Feature Summary

• Integrates five buck converters and one LDO regulator
• Supports surface-mount technology for compact designs
• Provides multi-rail power management in a single package

Applications

• Embedded systems requiring multiple voltage rails
• Consumer electronics power management
• Industrial control units

Procurement Notes

Verify the current manufacturing status as sources indicate this product may no longer be manufactured. Confirm package compatibility and pinout details against your schematic before procurement. Check for potential tariff implications if shipping to the United States. Ensure the supplier provides valid traceability documentation for this discontinued or end-of-life component.

Selection Notes

Select this component when a system requires five independent buck outputs and one LDO output within a limited board area. The 48-QFP package suits applications where space constraints prevent using discrete regulators. Evaluate thermal performance requirements as multiple switching regulators are housed in a single 7x7 mm footprint. Ensure input voltage ranges match the specific buck converter capabilities defined in the official datasheet.

Part Context

This part belongs to Epson's PMIC portfolio, specifically designed for integrated voltage regulation. It consolidates multiple power conversion stages into one chip, reducing component count and PCB layout complexity compared to discrete solutions. The integration of both switching and linear regulators offers flexibility for noise-sensitive analog circuits alongside digital logic supplies.

Replacement Considerations

As the component is noted as no longer manufactured, identify cross-compatible PMICs with matching pinouts and electrical specifications. Verify that replacement parts support five buck and one LDO configuration. Ensure package dimensions remain compatible with existing footprints.
