Industry's smallest 36-V, 1-A DC/DC step-down power module shrinks board space by up to 58 percent

Texas Instruments » LMZM23600, LMZM23601

Modules from Texas Instruments feature tiny MicroSiP packaging and achieve up to 92 percent efficiency

Texas Instruments (TI) introduced two new 4-V to 36-V power modules that measure just 3.0 mm by 3.8 mm and require only two external components for operation. The 0.5-A LMZM23600 and 1-A LMZM23601 DC/DC step-down converters achieve up to 92 percent efficiency, which minimizes energy loss, and feature tiny MicroSiP™ packaging that shrinks board space by up to 58 percent. The converters expand TI's power module portfolio to address up to 1-A performance-driven, space-constrained communication and industrial designs, including field transmitters, ultrasound scanners and network security cameras.

Texas Instruments - LMZM23600, LMZM23601

The LMZM23600 and LMZM23601 modules are offered with either fixed 5-V or 3.3-V output voltages, or with external synchronization and adjustable 2.5-V to 15-V output voltages. The LMZM23601 features a mode pin that allows flexibility to operate at a fixed frequency for low electromagnetic interference (EMI), or an automatic pulse frequency modulation control mode for high efficiency at light loads.

Key features and benefits of the LMZM23600 and LMZM23601

  • Provides 92 percent peak efficiency and 85 percent full-load efficiency for 24-V to 5-V power conversions.
  • 30-µA quiescent current increases light-load efficiency and extends battery life in battery-powered applications.
  • Small, 10-pin, 3.0-mm-by-3.8-mm-by-1.6-mm MicroSiP package with integrated inductor enables a complete fixed 3.3-V or 5-V output solution measuring just 27 mm2. With only two external components, the module reduces solution size by up to 58 percent when compared to a discrete solution with similar input and output voltages, output current and switching frequency.
