Description

The LMZM23601integrated-inductor power module is specifically designed for space-constrained industrialapplications. It is available in two fixed output voltage options of 5-V and 3.3-V, and anadjustable (ADJ) output voltage option supporting a 1.2-V to 15-V range. The LMZM23601 has an input voltage rangeof 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 theLMZM23601 are optimized forperformance 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 foran additional supervisory component, saving cost and board space. Seamless transition between PWMand PFM modes along with a no-load supply current of only 28 μA ensures high efficiency andsuperior transient response for the entire load-current range. For easy output current scaling theLMZM23601 is pin-to-pincompatible with the 500-mA output current capable LMZM23600.
