LM5067MM-2

The LM5067MM-2 is a Texas Instruments quad PWM controller used to build multi‑output buck regulators. It provides four current‑mode PWM control channels that drive external MOSFETs to generate multiple rails from a single input. Each channel can be configured with its own feedback path for tight cross‑regulation across outputs. Features typically include programmable switching frequency, enable/UVLO, soft‑start, and protections such as cycle‑by‑cycle current limit, overvoltage/overtemperature, and thermal shutdown. It relies on external inductors, diodes or synchronous FETs, and feedback networks to set output voltages. The MM‑2 suffix indicates a specific packaging/option set within the LM5067 family. Common applications are telecom, data‑center, and industrial power supplies needing several regulated rails from one input, with reduced board area versus discrete solutions. For exact specs, pinout, and application guidance, refer to the TI datasheet.

Do you want cross-references within TI only or with other manufacturers? Also please share your application specs (input voltage range, number of outputs/current, required switching frequency, and package). With those, I can provide exact equivalents or the closest drop-in substitutes (e.g., other high-voltage buck/boost controllers from TI or from Analog Devices, LTC, etc.).

LM5067MM-2 is a dual-channel high-voltage, constant-current LED driver. Key features typically include:

LM5067MM-2 is a dual-channel hot-swap and DC-DC converter controller. Typical application areas include:
- Hot-swap protection and input-stage control for rack/telecom/network equipment (servers, switches, storage)
- Front-end front-ends for dual-rail DC-DC converters in data centers and enterprise systems
- Power-supply stages for industrial automation and motor-drive systems
- Automotive and other battery-powered applications needing robust fault protection
- Isolated or nonisolated switching regulators and PMIC front ends
These use cases capitalize on its dual-channel protection and switching-regulator control capabilities.
