What are the key features of LM5023MM-2/NOPB?
- Current-mode PWM control with cycle-by-cycle current limiting for inherent overcurrent protection
- Wide 8 V to 14 V input range supporting standard 12 V bus power supplies in industrial and telecom designs
- Up to 630 kHz switching frequency enabling smaller transformer and filter component selection
- Compact 8-pin SOIC package with e3 JEDEC qualification for automated high-volume assembly
What is LM5023MM-2/NOPB used for?
The LM5023MM-2 is ideal for offline flyback power supplies and isolated DC-DC converters in industrial equipment and telecommunications infrastructure, where its current-mode PWM control simplifies loop compensation and provides fast transient response. It is also used in boost and forward converter topologies for 12 V distributed power rails operating up to 630 kHz, enabling compact magnetic components. Its 8 V to 14 V operating range makes it a natural fit for 12 V bus-powered modules in factory automation and embedded computing.

Frequently Asked Questions
What switching frequency range does the LM5023MM-2/NOPB support, and how does it affect magnetics sizing?
The LM5023MM-2 supports switching frequencies up to 630 kHz, which allows power supply designers to use significantly smaller transformers and inductors compared to lower-frequency controllers running at 100 kHz. At 400 kHz to 630 kHz, transformer core volume can be reduced by 50% or more, benefiting compact industrial and telecom power modules.
What input voltage range does the LM5023MM-2 accept, and is it compatible with a standard 12 V power bus?
The LM5023MM-2 operates from an input supply voltage of 8 V to 14 V, which makes it directly compatible with the standard 12 V distribution bus used in industrial control panels, server power systems, and telecom equipment. The controller requires only a simple 12 V rail to start up and regulate its internal bias, simplifying the overall power architecture.
How does current-mode control in the LM5023MM-2 benefit flyback converter designs compared to voltage-mode control?
Current-mode control in the LM5023MM-2 provides cycle-by-cycle peak current limiting, which protects the power switch and transformer from saturation under overload conditions without additional external circuits. It also simplifies feedback loop compensation to a single-pole design, reducing the component count needed to achieve stable regulation at output voltages from 3.3 V to 48 V in flyback topologies.
How does the 8-pin SOIC package of the LM5023MM-2 compare to larger controller packages for board density?
The 8-pin SOIC package of the LM5023MM-2 occupies approximately 5 mm × 4 mm of PCB area, which is roughly 40% smaller than a 16-pin SOIC controller providing equivalent functionality. This compact footprint makes it easy to place close to the power switch gate and current sense resistor in dense switching power supply layouts operating at 8 V to 14 V input.
