LM26400YSNVS457D –FEBRUARY 2007–REVISED OCTOBER 2015
LM26400Y Dual 2-A, 500-kHz Wide Input Range Buck Regulator Features 3 DescriptionThe LM26400Y deviceisa monolithic, two-output Input Voltage Rangeof3Vto20V fixed-frequency PWM step-down DC-DC regulator,in• Dual 2-A Output a 16-pin WSON or thermally-enhanced HTSSOP• Output Voltage Downto 0.6V package. With a minimum number of external
components and internal loop compensation, the• Internal Compensation LM26400Yis easyto use.• 500-kHz PWM Frequency
The abilityto drive 2-A loads with an internal 175-mΩ• Separate Enable Pins NMOS switch using state-of-the-art 0.5-µm BiCMOS• Separate Soft-Start Pins technology resultsina high-power density design.• Frequency Foldback Protection The world class control circuitry allows for an ON-
time as lowas 40 ns, thus supporting high-frequency• 175-mΩ NMOS Switch
conversion over the entire input rangeof3Vto20V• Integrated Bootstrap Diodes and downto an output voltageof only 0.6V. The• Overcurrent Protection LM26400Y utilizes peak current-mode control and HTSSOP and WSON Packages internal compensationto provide high-performance
regulation overa wide range of line and load• Thermal Shutdown conditions. Switching frequencyis internally setto
500 kHz, optimal fora broad rangeof applicationsin
2 Applications termsof size versus thermal tradeoffs. DTV-LCD Givena nonsynchronous architecture, efficiencies• Set-Top Boxes above 90% are easyto achieve. External shutdownis XDSL included, enabling separate turnon and turnoffof the
two channels. Additional features include• Automotive programmable soft-start circuitry to reduce inrush• Computing Peripherals current, pulse-by-pulse current limit and frequency• Industrial Controls foldback, integrated bootstrap structure, and thermal
shutdown.• Points-of-Load
