LM26400Y Dual 2-A, 500-kHz Wide Input Range Buck Regulator  
1 Features  
3 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  
1
Input Voltage Range of 3 V to 20 V  
Dual 2-A Output  
Output Voltage Down to 0.6 V  
Internal Compensation  
package. With  
a minimum number of external  
components and internal loop compensation, the  
LM26400Y is easy to use.  
500-kHz PWM Frequency  
Separate Enable Pins  
The ability to drive 2-A loads with an internal 175-m  
NMOS switch using state-of-the-art 0.5-µm 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 3 V to 20 V  
and down to an output voltage of only 0.6 V. The  
LM26400Y utilizes peak current-mode control and  
internal compensation to provide high-performance  
regulation over a wide range of line and load  
conditions. Switching frequency is internally set to  
500 kHz, optimal for a broad range of applications in  
terms of size versus thermal tradeoffs.  
Separate Soft-Start Pins  
Frequency Foldback Protection  
175-mNMOS Switch  
Integrated Bootstrap Diodes  
Overcurrent Protection  
HTSSOP and WSON Packages  
Thermal Shutdown  
2 Applications  
DTV-LCD  
Given a nonsynchronous architecture, efficiencies  
above 90% are easy to achieve. External shutdown is  
included, enabling separate turnon and turnoff of the  
Set-Top Boxes  
XDSL  
two  
channels.  
Additional  
features  
include  
Automotive  
programmable soft-start circuitry to reduce inrush  
current, pulse-by-pulse current limit and frequency  
foldback, integrated bootstrap structure, and thermal  
shutdown.
