1A, 40V, MAXPower Step-Down  
DC-DC Converters  
General Description  
Features  
The MAX5080/MAX5081 are 250kHz PWM step-down  
DC-DC converters with an on-chip, 0.3Ω high-side  
switch. The input voltage range is 4.5V to 40V for the  
MAX5080 and 7.5V to 40V for the MAX5081. The output  
is adjustable from 1.23V to 32V and can deliver up to  
1A of load current.  
♦ 4.5V to 40V (MAX5080) or 7.5V to 40V (MAX5081)  
Input Voltage Range  
♦ 1A Output Current  
♦ V  
Range From 1.23V to 32V  
OUT  
♦ Internal High-Side Switch  
Both devices utilize a voltage-mode control scheme for  
good noise immunity in the high-voltage switching envi-  
ronment and offer external compensation allowing for  
maximum flexibility with a wide selection of inductor val-  
ues and capacitor types. The switching frequency is  
internally fixed at 250kHz and can be synchronized to  
an external clock signal through the SYNC input. Light  
load efficiency is improved by automatically switching  
to a pulse-skip mode.  
♦ Fixed 250kHz Internal Oscillator  
♦ Automatic Switchover to Pulse-Skip Mode at  
Light Loads  
♦ External Frequency Synchronization  
♦ Thermal Shutdown and Short-Circuit Protection  
♦ Operates Over the -40°C to +125°C Temperature  
All devices include programmable undervoltage lock-  
out and soft-start. Protection features include cycle-by-  
cycle current limit, hiccup-mode output short-circuit  
protection, and thermal shutdown. Both devices are  
available in a space-saving, high-power (2.7W), 16-pin  
TQFN package and are rated for operation over the  
-40°C to +125°C temperature range.
