LM26400Y  
Dual 2A, 500kHz Wide Input Range Buck Regulator  
General Description  
Features  
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 ex-  
ternal components and internal loop compensation, the  
LM26400Y is easy to use. The ability to drive 2A loads with  
an internal 175mNMOS 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 to 20V and down to an output voltage  
of only 0.6V. The LM26400Y utilizes peak current-mode con-  
trol and internal compensation to provide high-performance  
regulation over a wide range of line and load conditions.  
Switching frequency is internally set to 500kHz, optimal for a  
broad range of applications in terms of size versus thermal  
tradeoffs. Given a non-synchronous architecture, efficiencies  
above 90% are easy to achieve. External shutdown is includ-  
ed, enabling separate turn-on and turn-off of the two chan-  
nels. Additional features include programmable soft-start  
circuitry to reduce inrush current, pulse-by-pulse current limit  
and frequency foldback, integrated bootstrap structure and  
thermal shutdown.  
Input voltage range of 3-20V
