Synchronous DC/DC converter design made easier

With its low BOM count, internal compensation and pin compatibility, the SIMPLE SWITCHER LMR23630/25/10 DC/DC buck converter family makes it easier than ever to leverage the enhanced performance of a synchronous regulator.

In addition to the improved efficiency performance afforded by synchronous rectification, the LMR236xx supports high VIN step-down to the load voltage at 2.1 MHz switching frequency. The family also offers low quiescent current operation to support battery powered systems.

With the combination of high performance and simplicity, LMR236xx is an easy choice for your next power supply design.

Key product highlights

  • Wide VIN range: Provides transient protection up to 36 V
  • Low pin-count: Simplifies design process and reduces required number of external components
  • 2.1 MHz operation: 60 ns minimum on-time allows high input/output ratio at high frequencies
  • Internal compensation: Simplifies the design process and reduces BOM count and solution cost
  • Pin compatible: Easy to re-use design for a wide variety of applications

Best-in-class non-synchronous DC/DC converters

The SIMPLE SWITCHER 60V LMR160x0 and 40V LMR140x0 DC/DC converter families set a new standard for non-synchronous buck regulators. Pin-compatibility offers scalability from 2 A to 5 A at 40 VIN and from 1 A to 3 A at 60 VIN. And with such wide input voltage ranges, these families not only fit a wide variety of applications, but are also ideal for robust designs requiring transient protection. Along with the ease of use expected from SIMPLE SWITCHER, these converters also feature low quiescent current, switching frequencies up to 2.5 MHz, high duty cycle support, and internal compensation.

Key product highlights

  • Wide VIN range: Provides transient protection up to 60V
  • Low quiescent current: Improves light load efficiency and extends battery life
  • Switching frequency up to 2.5 Mhz: Flexibility to adjust frequency to avoid certain bands
  • Internal compensation: Simplifies the design process and reduces BOM count and solution cost
  • Pin compatible: Easy to re-use design for a wide variety of applications
