19-1835; Rev 0; 10/00  
Small, Dual, High-Efficiency  
Buck Controller for Notebooks  
General Description  
Features  
The MAX1761 dual pulse-width-modulation (PWM),  
step-down controller provides high efficiency, excellent  
transient response, and high DC output accuracy in an  
extremely compact circuit topology. These features are  
essential for stepping down high-voltage batteries to  
generate low-voltage CPU core, I/O, and chipset RAM  
supplies in PC board area critical applications, such as  
notebook computers and smart phones.  
o Free-Running On-Demand PWM  
o Selectable Light-Load Pulse-Skipping Operation  
o ±±1 ꢀotal Dꢁ ꢂrror in Forced-PWM Mode  
o 5V to 20V Input Range  
o Flexible Output Voltages  
OUꢀ±: Dual Mode™ Fixed 2.5V or ±V to 5.5V  
Adjustable  
Maxim’s proprietary Quick-PWM™ quick-response,  
constant-on-time PWM control scheme handles wide  
input/output voltage ratios with ease and provides  
“instant-on” response to load transients while maintain-  
ing a relatively constant switching frequency.  
OUꢀ2: Dual Mode Fixed ±.8V or ±V to 5.5V  
Adjustable  
o Output Undervoltage Protection  
o ꢁomplementary Synchronous Buck  
o No ꢁurrent-Sense Resistor  
The MAX1761 achieves high efficiency at reduced cost  
by eliminating the current-sense resistor found in tradi-  
tional current-mode PWMs. Efficiency is further  
enhanced by its ability to drive large synchronous-recti-  
fier MOSFETs. The MAX1761 employs a complemen-  
tary MOSFET output stage, which reduces component  
count by eliminating external bootstrap capacitors and  
diodes.  
o 4.65V at 25mA Linear Regulator Output  
o 4µA V+ Shutdown Supply ꢁurrent  
o 5µA VL Shutdown Supply ꢁurrent  
o 950µA Quiescent Supply ꢁurrent  
o ꢀiny ±6-Pin QSOP Package  
Single-stage buck conversion allows this device to  
directly step down high-voltage batteries for the highest  
possible efficiency. Alternatively, two-stage conversion  
(stepping down the +5V system supply instead of the  
battery) at a higher switching frequency allows the mini-  
mum possible physical size.  
The MAX1761 is intended for CPU core, chipset,  
DRAM, or other low-voltage supplies. The MAX1761 is  
available in a 16-pin QSOP package. For applications  
requiring greater output power, refer to the MAX1715  
data sheet. For a single-output version, refer to the  
MAX1762/MAX1791 data sheet.
