2A, 76V, High-Efficiency  
MAXPower Step-Down DC-DC Converters  
General Description  
Features  
♦ Wide Input Voltage Range: 6.5V to 76V  
The MAX5090A/B/C easy-to-use, high-efficiency, high-  
voltage step-down DC-DC converters operate from an  
input voltage up to 76V, and consume only 310µA qui-  
escent current at no load. This pulse-width-modulated  
(PWM) converter operates at a fixed 127kHz 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 MAX5090  
includes internal frequency compensation simplifying  
circuit implementation. The device can also be syn-  
chronized with external system clock frequency in a  
noise-sensitive application. The MAX5090 uses an  
internal low on-resistance and a high-voltage DMOS  
transistor to obtain high efficiency and reduce overall  
system cost. This device includes undervoltage lock-  
out, cycle-by-cycle current limit, hiccup-mode output  
short-circuit protection, and overtemperature shutdown.  
♦ Fixed (3.3V, 5V) and Adjustable (1.265V to 11V)  
Output-Voltage Versions  
♦ 2A Output Current  
♦ Efficiency Up to 92%  
♦ Internal 0.26Ω High-Side DMOS FET  
♦ 310µA Quiescent Current at No Load  
♦ 19µA Shutdown Current  
♦ Internal Frequency Compensation  
♦ Fixed 127kHz Switching Frequency  
♦ External Frequency Synchronization  
♦ Thermal Shutdown and Short-Circuit Current Limit  
♦ -40°C to +125°C Automotive Temperature Range  
♦ 16-Pin (5mm x 5mm) Thin QFN Package  
♦ Capable of Dissipating 2.67W at +70°C  
The MAX5090 delivers up to 2A output current. External  
shutdown is included, featuring 19µA (typ) shutdown  
current. The MAX5090A/MAX5090B versions have fixed  
output voltages of 3.3V and 5V, respectively, while the  
MAX5090C features an adjustable 1.265V to 11V output  
voltage.
