Up to 750mA Load Currents  
The MAX750A/MAX758A are adjustable-output, CMOS,  
s te p -d own, DC-DC s witc hing re g ula tors . The  
MAX758A accepts inputs from 4V to 16V and delivers  
750mA, while the MAX750A accepts inputs from 4V to  
11V and delivers 450mA. Typical efficiencies are 85%  
to 90%. Typical quiescent current is 1.7mA, or only  
6µA in shutdown mode. The output does not exhibit  
any ripple at subharmonics of the switching frequency  
over its specified range.

Adjustable Output Voltage  
Pulse-width-modulation (PWM) current-mode control  
provides precise output regulation and excellent tran-  
sient responses. Output voltage accuracy is guaran-  
teed to be ±4.5% plus feedback-resistor tolerance over  
line, load, and temperature variations. Fixed-frequency  
switching and absence of subharmonic ripple allows  
easy filtering of output ripple and noise, as well as the  
use of small external components. These regulators  
require only a single inductor value to work in most  
applications, so no inductor design is necessary.
