Board space can be reduced by up to 58%

TI announced the release of two new 4V to 36V power module products that are only 3.0mm x 3.8mm in size and require only two external components.

The 0.5A LMZM23600 and 1A LMZM23601 DC/DC step-down converters achieve up to 92% efficiency to minimize energy loss and utilize ultra-small MicroSiP packaging to reduce board space by up to 58%. By adding these converter products to TI's power module portfolio, the requirements of space-constrained communications and industrial designs aiming for 1A performance, such as field transmitters, ultrasonic scanners, and network security cameras, are now met.

TI plans to demonstrate the 1A LMZM23601 power module at the Applied Power Electronics Conference (APEC) exhibition held in San Antonio, Texas, from March 6 to 8.

The LMZM23600 and LMZM23601 modules provide a fixed 5V or 3.3V output voltage or an adjustable output voltage from 2.5V to 15V using external synchronization. Additionally, the LMZM23601 includes a mode pin, allowing it to operate at a fixed frequency to reduce electromagnetic interference (EMI) or in an automatic pulse frequency modulation control mode to achieve high efficiency under light loads.

The LMZM23600 and LMZM23601 modules achieve 92% peak efficiency and 85% full-load efficiency with 24V to 5V power conversion. With a standby current of 30 Ω, it enables improved light-load efficiency and extended battery life in battery-powered applications. An ultra-small 10-pin 3.0 mm x 3.8 mm x 1.6 mm MicroSiP package integrating an inductor allows for a complete 3.3 V or 5 V output solution to be implemented in a footprint of just 27 mm². Since it requires only two external components, the solution size can be reduced by up to 58% compared to discrete solutions while maintaining the same input/output voltage, output current, and switching frequency.
