Automotive-grade dual 2 A buck for point-of-load rails
The LM26420Q1XSQX/NOPB: The 2.2 MHz switching frequency allows the use of small inductors and ceramic capacitors, shrinking the total solution footprint for space-constrained automotive ECUs.
Package and thermal integration for compact boards
Housed in a 16-WQFN with an exposed pad (4 mm × 4 mm), the LM26420Q1XSQX/NOPB requires a thermal land pattern on the PCB to dissipate heat from the dual 2 A outputs. The adjustable output voltage range from 0.8 V to 4.5 V covers common core and I/O rails for microcontrollers, FPGAs, and sensors in automotive infotainment and ADAS modules.
