_______________Ge n e ra l De s c rip t io n  
____________________________Fe a t u re s  
The MAX1626/MAX1627 step-down DC-DC switching  
controllers provide high efficiency over loads ranging  
from 1mA to more than 2A. A unique current-limited,  
p uls e -fre q ue nc y-mod ula te d (PFM) c ontrol s c he me  
operates with up to a 100% duty cycle, resulting in very  
low dropout voltages. This control scheme eliminates  
minimum load requirements and reduces the supply  
current under light loads to 90µA (versus 2mA to 10mA  
for common pulse-width modulation controllers).  
Low Dropout Voltage  
100% Maximum Duty Cycle  
Soft-Start Limits Start-Up Current  
Efficiency >90% (3mA to 2A Loads)  
Output Power >12.5W  
90µA Max Quiescent Current  
1µA Max Shutdown Current  
Up to 300kHz Switching Frequency  
16.5V Max Input Voltage  
These step-down controllers drive an external P-chan-  
nel MOSFET, allowing design flexibility for applications  
to 12W or higher. Soft-start reduces current surges dur-  
ing start-up. A high switching frequency (up to 300kHz)  
and operation in continuous-conduction mode allow the  
use of tiny surface-mount inductors. Output capacitor  
requirements are also reduced, minimizing PC board  
area and system costs.  
Output Voltage: 5V/3.3V (MAX1626)  
Adjustable (MAX1627)  
Current-Limited Control Scheme  
The outp ut volta g e is p re s e t a t 5V or 3.3V for the  
MAX1626 and adjustable for the MAX1627. Input volt-  
ages can be up to 16.5V. The MAX1626/MAX1627 are  
functional upgrades for the MAX1649/MAX1651.
