Description
xProduct Overview: LX7178-03CSP
Engineered for high-current power delivery in ultra-compact electronic assemblies, the LX7178-03CSP is a premium 5A synchronous buck switching regulator manufactured by Microsemi. This device operates within a flexible input range of 3V to 5.5V, delivering a stable output voltage adjustable from 0.6V to 3.3V. Driven by a high 1.875MHz switching frequency, it enables the use of miniature surface-mount inductors and capacitors, significantly reducing the overall printed circuit board (PCB) footprint. Optimized for high-density storage systems, enterprise servers, and advanced networking hardware, the LX7178-03CSP ensures superior thermal efficiency and minimal power loss. AICCHIP supports global B2B procurement by supplying authentic, factory-original ICs dispatched directly from our professional distribution hubs in China.
Highlighted Advantages
- High-Current Capability: Supports up to 5A of continuous output current, providing robust power for modern low-voltage microprocessors and FPGAs.
- Integrated Synchronous Rectification: Maximizes power conversion efficiency by eliminating the need for an external Schottky diode, reducing heat generation in sensitive embedded systems.
- Ultra-Compact WLCSP Packaging: Housed in a space-saving 20-pin Wafer Level Chip Scale Package (WLCSP), it offers an optimal balance between electrical performance and extreme physical miniaturization.
- Programmable Versatility: Features a programmable (Fixed) output configuration, allowing design engineers to fine-tune power rails for specific high-performance applications.
