DC/DC step down power module shrinks board space by up to 58%

Two new 4-36-V power modules that measure just 3.0x3.8mm and require only two external components for operation have been introduced by Texas Instruments.

The 0.5A LMZM23600 and 1A LMZM23601 DC/DC step-down converters achieve up to 92% efficiency, which minimises energy loss, and feature tiny MicroSiP packaging that shrinks board space by up to 58%.

The converters expand TI’s power module portfolio to address up to 1A performance-driven, space-constrained communication and industrial designs, including field transmitters, ultrasound scanners and network security cameras.

TI will demonstrate the 1A LMZM23601 power module in booth 501 at the Applied Power Electronics Conference (APEC) in San Antonio, Texas, 6th-8th March 2018.

The LMZM23600 and LMZM23601 modules are offered with either fixed 5V or 3.3V output voltages, or with external synchronisation and adjustable 2.5V to 15V 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.
