2A, 40V Step-Down DC-DC Converter with  
Dynamic Output-Voltage Programming  
MAX1520  
General Description  
Features  
o Wide 7.5V to 40V Input Voltage Range  
The MAX15020 high-voltage step-down DC-DC con-  
verter operates over an input voltage range of 7.5V to  
40V. The device integrates a 0.2high-side switch and  
is capable of delivering 2A load current with excellent  
load and line regulation. The output is dynamically  
adjustable from 0.5V to 36V through the use of an exter-  
nal reference input (REFIN). The MAX15020 consumes  
only 6µA in shutdown mode.  
o 2A Output Current, Up to 96% Efficiency  
o Dynamic Programmable Output Voltage (0.5V to  
36V)  
o Maximum Duty Cycle of 95% (typ) at 300kHz  
o 100kHz to 500kHz Synchronizable SYNC  
Frequency Range  
The device utilizes feed-forward voltage-mode architec-  
ture for good noise immunity in the high-voltage switch-  
ing environment and offers external compensation for  
maximum flexibility. The switching frequency is selec-  
table to 300kHz or 500kHz and can be synchronized to  
an external clock signal of 100kHz to 500kHz by using  
the SYNC input. The IC features a maximum duty cycle  
of 95% (typ) at 300kHz.  
o Configurable UVLO and Soft-Start  
o Low-Noise, Voltage-Mode Step-Down Converter  
o Programmable Output-Voltage Slew Rate  
o Lossless Constant Current Limit with Fixed  
Timeout to Hiccup Mode  
o Extremely Low-Power Consumption (< 6µA typ) in  
The device includes configurable undervoltage lockout  
(UVLO) and soft-start. Protection features include  
cycle-by-cycle current limit, hiccup-mode for output  
short-circuit protection, and thermal shutdown. The  
MAX15020 is available in a 20-pin TQFN 5mm x 5mm  
package and is rated for operation over the  
-40°C to +125°C temperature range.
