1A, 76V, High-Efficiency MAXPower  
Step-Down DC-DC Converter  
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 350µA 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  
ꢀ 350µA 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. 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.
