What are the key features of LM26400YSDE?

  • Dual independent 2A buck regulators in a single IC reduce BOM count and PCB area versus discrete solutions
  • Wide 3V to 20V input voltage range supports a broad variety of power sources from single-cell Li-ion to industrial 12V or 19V rails
  • Current-mode PWM control delivers fast transient response and inherent cycle-by-cycle overcurrent protection
  • 16-pin WSON leadless package minimizes inductance and thermal resistance for high-efficiency power conversion
  • Supports 5V nominal input for compatibility with standard USB and regulated bus supply voltages

What is LM26400YSDE used for?

The LM26400YSDE is designed for point-of-load power conversion in industrial equipment, communications infrastructure, and embedded computing platforms requiring multiple regulated output voltages from a single supply. Its dual-output architecture makes it ideal for powering processor cores and memory rails simultaneously in FPGAs, DSPs, and application processors. The wide input range also suits automotive accessories, test equipment, and multi-rail power supply designs where a single regulator IC must serve diverse voltage requirements.
