TI: 1-A DC/DC step-down power modules feature tiny MicroSiP packaging

Texas Instruments two new 4-V to 36-V power modules that measure just 3.0 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. TI will demonstrate the 1-A LMZM23601 power module at the Applied Power Electronics Conference (APEC).

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, or an automatic pulse frequency modulation control mode for high efficiency at light loads.
