LM26420XMH/NOPB is a dual 2 A synchronous buck regulator for compact 3 V to 5.5 V power rails, operating at 2.2 MHz in a 20-pin HTSSOP package.

Best for

  • Dual low-voltage rails from a 3 V to 5.5 V source
  • FPGA, ASIC, CPU, and digital core power rails
  • Space-constrained designs needing 2.2 MHz switching

Avoid if

  • Input voltage exceeds 5.5 V
  • A single output requires more than 2 A continuous current
  • The design cannot provide adequate PCB thermal copper and exposed-pad grounding

Check before use

  • Confirm output voltage and duty-cycle margin at minimum input voltage
  • Select inductors with adequate saturation-current rating
  • Place input capacitors close to VIND and PGND pins
  • Connect the exposed pad to ground with thermal vias
