open-in-new Find other Buck modules (integrated inductor)

Description

The LMZM23601 integrated-inductor power module is specifically designed for space-constrained industrial applications. It is available in two fixed output voltage options of 5-V and 3.3-V, and an adjustable (ADJ) output voltage option supporting a 1.2-V to 15-V range. The LMZM23601 has an input voltage range of 4-V to 36-V and can deliver up to 1000-mA of output current. This power module is extremely easy to use, requiring only 2 external components for a 5-V or 3.3-V output design. All aspects of the LMZM23601 are optimized for performance driven and low EMI industrial applications with space-constrained needs. An open-drain, Power-Good output provides a true indication of the system status and negates the requirement for an additional supervisory component, saving cost and board space. Seamless transition between PWM and PFM modes along with a no-load supply current of only 28 µA ensures high efficiency and superior transient response for the entire load-current range. For easy output current scaling the LMZM23601 is pin-to-pin compatible with the 500-mA output current capable LMZM23600.
