DC Switching Voltage Regulators

LM26420YSQX/NOPB Description

The LM26420YSQX/NOPB from Texas Instruments is a high-efficiency, dual-output synchronous buck regulator designed for compact, power-sensitive applications. Operating within a 3V to 5.5V input range, it delivers two adjustable outputs (up to 4.5V each) with a robust 2A per channel current capability. The device integrates a 550kHz fixed-frequency PWM controller, ensuring stable performance while minimizing external component count. Packaged in a 16-pin WQFN (3mm x 3mm) and compliant with ROHS3 and REACH standards, it is ideal for space-constrained designs requiring high power density.

LM26420YSQX/NOPB Features

• Dual Adjustable Outputs: Independent voltage regulation (0.8V to 4.5V) for versatile power management.
• High Efficiency: Synchronous rectification reduces power losses, achieving peak efficiency >90%.
• Compact Design: Integrated MOSFETs and 550kHz switching frequency enable smaller inductors and capacitors.
• Robust Protection: Includes thermal shutdown, overcurrent protection, and undervoltage lockout (UVLO).
• Low Noise Operation: Optimized for sensitive analog/digital loads with minimal EMI.
• MSL3 Rated: Suitable for extended storage (168 hours) before reflow.

LM26420YSQX/NOPB Applications

• Portable Electronics: Smartphones, tablets, and wearables benefit from its low quiescent current and small footprint.
• Embedded Systems: Ideal for FPGA, DSP, and microcontroller power rails in industrial/automotive applications.
• Point-of-Load (PoL) Regulation: Provides precise voltage scaling for sensors, memory, and RF modules.
• Battery-Powered Devices: Efficiently manages dual-voltage requirements in handheld instruments or IoT nodes.

Conclusion of LM26420YSQX/NOPB

The LM26420YSQX/NOPB stands out for its dual-output flexibility, high efficiency, and compact form factor, making it a superior choice for modern power designs. Its integration of synchronous rectification and protection features ensures reliability in demanding environments, while the adjustable outputs cater to diverse voltage needs. Engineers targeting space-constrained, battery-operated, or noise-sensitive systems will find this regulator an optimal solution.
