Visão Geral
Description
The LM5085MM is a buck switching regulator IC from Texas Instruments, designed for wide input voltage (4.5V to 75V) applications. It integrates a high-side N-channel MOSFET driver, enabling efficient step-down (buck) DC-DC conversion with adjustable output voltage.
Key features:
- Peak current-mode control for fast transient response.
- Adjustable switching frequency (50kHz–1MHz) for flexibility in design.
- Low shutdown current (<3µA) for power-saving modes.
- Thermal shutdown & cycle-by-cycle current limiting for protection.
Typical applications include industrial, automotive, and telecom power supplies. The MM (VSSOP-8) package makes it suitable for space-constrained designs.
For detailed specs, refer to the datasheet or TI’s product page.
