±1% DC Accuracy (Adjustable Mode)  
Output Overvoltage Crowbar Protection  
Output Undervoltage Shutdown  
The MAX1636 is a synchronous, buck, switch-mode,  
power-supply controller that generates the CPU supply  
voltage in battery-powered systems. It achieves ±1%  
output voltage accuracy and offers the excellent load-  
transient response needed by upcoming generations of  
dynamic-clock CPUs.  
Adjustable Switching Frequency to 340kHz  
Low-Dropout Operation  
Up to 95% efficiency is achieved through synchronous  
rectification and Maxims proprietary Idle Mode™ con-  
trol s c he me . Effic ie nc y is g re a te r tha n 80% ove r a  
1000:1 load-current range, extending battery life in sys-  
tem-suspend or standby modes. Excellent dynamic  
response corrects output load transients caused by the  
latest dynamic-clock CPUs within five 300kHz clock  
cycles. Strong, 1A, on-board gate drivers ensure fast,  
external N-channel MOSFET switching.  
Idle Mode Pulse-Skipping Operation  
1.10V to 5.5V Adjustable Output Voltage  
2.5V/3.3V Dual-Mode Fixed-Output Settings  
Internal Digital Soft-Start  
1.1V ±1% Reference Output  
3µA (typ) Shutdown Current  
The MAX1636 features a logic-controlled and synchro-  
nizable, fixed-frequency, pulse-width-modulation (PWM)  
operating mode that reduces noise and RF interference  
in sensitive mobile communications and pen-entry appli-  
cations. Holding SKIP high forces fixed-frequency mode  
for lowest noise under all load conditions.
