dual bucksynchronous regulator2 A per channel2.2 MHzWQFN-163 V to 5.5 V input

LM26420XSQX/NOPB is a dual 2 A synchronous buck regulator for 3 V to 5.5 V rails where compact 2.2 MHz conversion and independently controlled outputs are required.

Best for

  • Dual low-voltage rails from a 3 V to 5.5 V source
  • FPGA, CPU, ASIC, HDD, and set-top-box core supplies
  • Space-constrained power stages needing 2.2 MHz switching

Avoid if

  • Input voltage is outside 3 V to 5.5 V
  • More than 2 A continuous load is required on either channel
  • The design cannot provide low-inductance input bypassing and a thermal ground path

Check before use

  • Peak inductor current versus the 2.4 A minimum current limit
  • Output-voltage duty-cycle margin at minimum input voltage
  • WQFN exposed-pad soldering and thermal-via implementation
