High-Efficiency, 8A, Current-Mode Synchronous  
Step-Down Switching Regulator with VID Control  
General Description  
Features  
S Continuous 8A Output Current  
S Efficiency Over 90%  
The MAX15109 high-efficiency, current-mode, synchro-  
nous step-down switching regulator with integrated  
power switches deliver up to 8A of output current. This  
regulator operates from 2.7V to 5.5V and provides four  
output voltages using two VID control inputs.  
S
1% Accuracy Over Load, Line, and Temperature  
S Operates from a 2.7V to 5.5V Supply  
S VID Control Inputs for Selecting Output Voltage  
S Programmable Slew-Rate Control  
This IC utilizes a current-mode control architecture  
with a high gain transconductance error amplifier.  
The current-mode control architecture facilitates easy  
compensation design and ensures cycle-by-cycle  
current limit with fast response to line and load transients.  
S Safe Startup into Prebiased Output  
S 1MHz Switching Frequency  
S Stable with Low-ESR Ceramic Output Capacitors  
S Enable Input and Power-Good Output for Power-  
This regulator offers skip-mode functionality to reduce  
current consumption and achieve a higher efficiency at  
Supply Sequencing  
S Cycle-by-Cycle Overcurrent Protection Faults  
light loads. The low R  
integrated switches ensure  
DS(ON)  
high efficiency at heavy loads while minimizing critical  
inductance, making the layout design a much simpler  
task with respect to discrete solutions. The high switching  
frequency (1MHz), along with the PWM current-mode archi-  
tecture allows for a compact, all-ceramic capacitor design.  
S Fully Protected Against Overcurrent and  
Overtemperature  
S Input Undervoltage Lockout  
S 20-Bump (4 x 5 Array), 2.5mm x 2mm, WLP  
Package  
The IC features a capacitor-programmable slew-rate  
control to reduce input current at the startup and when  
the output changes state under VID control. Internal  
control circuitry ensures safe-startup into a prebiased  
output. Power sequencing is controlled with the enable  
input and power-good output.
