LM26400Y Dual 2A, 500kHz Wide Input Range Buck Regulator February 2007 LM26400Y Dual 2A, 500kHz Wide Input Range Buck Regulator General Description The LM26400Y is a monolithic, two-output fixed frequency PWM step-down DC/DC regulator in a 16-pin LLP or thermally enhanced ETSSOP package. With a minimum number of external ponents and internal loop pensation, the LM26400Y is easy to use. The ability to drive 2A loads with an internal 175mΩ NMOS switch using state-of-the-art 0.5µm BiCMOS technology results in a high-power density design. The world class control circuitry allows for an ON-time as low as 40 ns, thus supporting high-frequency conversion over the entire input range of 3V...
