LMZM23601SILR Description

The integrated-inductor power module LMZM23601SILR was created especially for industrial applications with limited space. It has two fixed output voltage options of 5 V and 3.3 V, as well as an adjustable (ADJ) output voltage option that supports a range of 1.2 V to 15 V. The LMZM23601SILR can deliver up to 1000 mA of output current and has an input voltage range of 4-V to 36-V. Due to the fact that it only needs 2 external components for a 5-V or 3.3-V output design, this power module is incredibly simple to operate. The LMZM23601SILR is designed with performance-driven, low EMI industrial applications with space-constrained requirements in mind.

A real indicator of the system state is provided via an open-drain, Power-Good output, which also eliminates the need for an additional supervisory component, saving money and board space. High efficiency and excellent transient responsiveness are guaranteed for the full load-current range thanks to a smooth transition between PWM and PFM modes and a no-load supply current of only 28 A. The LMZM23601 is pin-to-pin compatible with the 500-mA output current capability LMZM23600 for simple output current scaling.
