📥 Download Datasheet

General Description

The LM26400Y device is a monolithic, two-output fixed-frequency PWM step-down DC-DC regulator, in a 16-pin WSON or thermally-enhanced HTSSOP package.

With a minimum number of external components and internal loop compensation, the LM26400Y is easy to use.

The ability to drive 2-A loads with an internal 175-mΩ NMOS switch using state-of-the-art 0.5-µm BiCMOS technology results in a high-power density design.
