WCDMA Cellular Phone 600mA  
Buck Regulators  
General Description  
Features  
The MAX1820/MAX1821 low-dropout, pulse-width-mod-  
ulated (PWM) DC-DC buck regulators are optimized to  
provide power to the PA in WCDMA cellphones; howev-  
er, they may be applied in many other applications  
where high efficiency is a priority. The supply voltage  
range is from 2.6V to 5.5V, and the guaranteed output  
current is 600mA. 1MHz PWM switching allows for  
small external components, while skip mode reduces  
quiescent current to 180µA with light loads.  
ꢀ Dynamically Adjustable Output from 0.4V to 3.4V  
(MAX1820)  
ꢀ Programmable Output from 1.25V to 5.5V  
(MAX1821)  
ꢀ SYNC to 13MHz External Clock (MAX1820X)  
ꢀ SYNC to 19.8MHz External Clock (MAX1820Y)  
ꢀ NO SYNC, Internal 1MHz Osculator (MAX1820Z)  
The MAX1820 is dynamically controlled to provide vary-  
ing output voltages from 0.4V to 3.4V. The circuit is  
designed such that the output voltage settles in <30µs  
for a full-scale change in voltage and current. The  
MAX1821 is set with external resistors to provide any  
fixed output voltage in the 1.25V to 5.5V range.  
ꢀ Low Quiescent Current  
180µA (typ) in Skip Mode  
0.1µA (typ) in Shutdown Mode  
ꢀ No External Schottky Diode Required  
ꢀ 600mA Guaranteed Output Current  
ꢀ 0% to 100% Duty-Cycle Operation  
The MAX1820/MAX1821 include a low on-resistance  
internal MOSFET switch and synchronous rectifier to  
maximize efficiency and minimize external component  
count. 100% duty-cycle operation allows for low dropout  
of only 150mV at 600mA load, including the external  
inductor resistance. The devices are offered in 10-pin  
ꢀ 150mV Dropout at 600mA Load (including R  
of external inductor)
