Frequently Asked Questions

What is the input voltage range of the LM3485MM?

The LM3485MM operates over an input voltage range of 4.5V to 35V, with a nominal operating voltage of 12V. This wide range makes it suitable for 5V, 12V, and 24V power systems commonly found in industrial and telecom applications.

What control technique does the LM3485MM use?

The LM3485MM uses hysteretic current-mode control, which provides inherently fast transient response and eliminates the need for complex loop compensation. It can also operate in adjustable PWM control mode, offering design flexibility for different load conditions.

What is the adjustable output voltage range of the LM3485MM?

In adjustable mode, the LM3485MM can regulate output voltage from 1.239V up to 35V, allowing designers to set the desired rail voltage using a simple resistor divider network on the feedback pin.

What package does the LM3485MM come in?

The LM3485MM is available in an 8-pin MSOP (S-PDSO-G8) small outline package, which provides a compact footprint ideal for space-constrained PCB layouts in portable and embedded power applications.

Where can I buy the LM3485MM and what is the price?

The LM3485MM is available from FindMyChip starting from $0.39 per unit. It is in stock and available for worldwide shipping, making it easy to source for both prototype and production quantities.
