750mA Load Currents (MAX738A/MAX744A)  
High-Frequency, Current-Mode PWM  
The MAX730A/MAX738A/MAX744A a re 5V-outp ut  
CMOS, step-down switching regulators. The MAX738A/  
MAX744A accept inputs from 6V to 16V and deliver  
750mA. The MAX744A guarantees 500mA load capa-  
bility for inputs above 6V and has tighter oscillator fre-  
quency limits for low-noise (radio) applications. The  
MAX730A accepts inputs between 5.2V and 11V and  
delivers 450mA for inputs above 6V. Typical efficien-  
c ie s a re 85% to 96%. Quie s c e nt s up p ly c urre nt is  
1.7mA and only 6µA in shutdown.

Pulse-width modulation (PWM) current-mode control  
provides precise output regulation and excellent tran-  
sient responses. Output voltage accuracy is guaran-  
teed to be ±5% over line, load, and temperature varia-  
tions. Fixed-frequency switching 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.
