Step-down DC/DC power modules cut board space by 58%

The 0.5A LMZM23600 and 1A LMZM23601 power modules are available in a fixed-output voltage of either 3.3V or 5V or with an adjustable output voltage of 2.5V to 15V.

They feature an integrated inductor and an input voltage range of 4V to 36V with up to 92% efficiency to minimise energy loss.

The modules’ 30µA quiescent current increases light-load efficiency and extends battery life in battery-powered applications.

Only two external components are required for fixed-output voltage performance, offering an easy-to-use solution for designers, as well as plug-and-play capability.

The power modules support a seamless transition between forced PWM mode and auto PFM mode, enabling both constant-frequency operations and high-efficiency operations with light loads.

They are optimised for low-EMI, performance-driven industrial applications and include built-in control loop compensation, soft start, current limit protection, and undervoltage lockout.

Both modules are supported by the LMZM23600 and LMZM23601 evaluation modules, fully assembled and tested modules that allow developers to evaluate the features and performance of the power modules.

The LMZM236000 evaluation module is available in all three output voltage options, while the LMZM23601 evaluation module is available in an adjustable 2.5 V to 15 V version.

Space-constrained designs such as sensor transmitters, grid infrastructure, field transmitters, ultrasound scanners, and network security cameras are targets for the power modules.
