Description
xProduct Overview: NX4108-33CZ1TR
Engineered for highly efficient power management in space-constrained layouts, the NX4108-33CZ1TR is a reliable synchronous buck switching regulator manufactured by Microsemi. This specific variant delivers a highly stable fixed 3.3V output, completely eliminating the need for external feedback resistors and thereby simplifying your circuit design. Capable of driving a continuous 1A output current, it operates at a rapid 1MHz switching frequency. This allows design engineers to utilize ultra-small, low-profile surface-mount inductors and capacitors. Housed in a compact SOT-23 package, it is the optimal solution for 5V to 3.3V step-down conversions in industrial controllers, network interfaces, and embedded systems. AICCHIP connects global B2B procurement teams directly to authentic, high-quality PMICs, ensuring a steady supply chain dispatched securely from China.
Highlighted Advantages
- Fixed 3.3V Precision: The factory-set 3.3V output drastically reduces the external component count on your bill of materials (BOM), saving critical printed circuit board (PCB) real estate.
- Integrated Synchronous Rectification: Delivers high-efficiency power conversion without requiring an external Schottky diode, which significantly reduces heat generation and lowers assembly costs.
- Ultra-Compact SOT-23 Form Factor: The minimalist package design is heavily optimized for densely populated boards in portable devices and compact industrial modules.
- 1MHz Switching Frequency: Facilitates the use of smaller filter components while maintaining excellent transient response and minimizing output voltage ripple.
