Texas Instruments has introduced two new 4 to 36V power modules that measure just 3.0×3.8mm and require only two external components for operation. The 0.5A LMZM23600 and 1A LMZM23601 DC/DC step-down converters achieve up to 92% efficiency, which minimizes 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 1-A LMZM23601 power module in booth No. 501 at the Applied Power Electronics Conference (APEC) in San Antonio, Texas, March 6-8, 2018. Read this blog post to find out about all of the products TI will unveil at APEC, as well as end-to-end power-management system solutions including hardware, software and reference designs that help engineers get to market quickly.
The LMZM23600 and LMZM23601 modules are offered with either fixed 5 or 3.3V output voltages, or with external synchronization and adjustable 2.5 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.
Key features and benefits of the LMZM23600 and LMZM23601
- Provides 92% peak efficiency and 85% full-load efficiency for 24 to 5V power conversions.
- 30µA quiescent current increases light-load efficiency and extends battery life in battery-powered applications.
- Small, 10-pin, 3.0×3.8×1.6mm MicroSiP package with integrated inductor enables a complete fixed 3.3 or 5V output solution measuring just 27mm2. With only two external components, the module reduces solution size by up to 58% when compared to a discrete solution with similar input and output voltages, output current and switching frequency.
