1A, 76V, High-Efficiency MAXPower  
Step-Down DC-DC Converter  
MAX035  
General Description  
Features  
The MAX5035 easy-to-use, high-efficiency, high-volt-  
age, step-down DC-DC converter operates from an  
input voltage up to 76V and consumes only 270µA qui-  
escent current at no load. This pulse-width modulated  
(PWM) converter operates at a fixed 125kHz switching  
frequency at heavy loads, and automatically switches  
to pulse-skipping mode to provide low quiescent cur-  
rent and high efficiency at light loads. The MAX5035  
includes internal frequency compensation simplifying  
circuit implementation. The device uses an internal low-  
on-resistance, high-voltage, DMOS transistor to obtain  
high efficiency and reduce overall system cost. This  
device includes undervoltage lockout, cycle-by-cycle  
current limit, hiccup mode output short-circuit protec-  
tion, and thermal shutdown.  
♦ Wide 7.5V to 76V Input Voltage Range  
♦ Fixed (3.3V, 5V, 12V) and Adjustable  
(1.25V to 13.2V) Versions  
♦ 1A Output Current  
♦ Efficiency Up to 94%  
♦ Internal 0.4Ω High-Side DMOS FET  
♦ 270µA Quiescent Current at No Load, 10µA  
Shutdown Current  
♦ Internal Frequency Compensation  
♦ Fixed 125kHz Switching Frequency  
♦ Thermal Shutdown and Short-Circuit Current  
The MAX5035 delivers up to 1A output current. The out-  
put current may be limited by the maximum power dis-  
sipation capability of the package. External shutdown is  
included, featuring 10µA (typ) shutdown current. The  
MAX5035A/B/C versions have fixed output voltages of  
3.3V, 5V, and 12V, respectively, while the MAX5035D  
features an adjustable output voltage from 1.25V to  
13.2V.
