EVALUATION KIT AVAILABLE  
MAX20735  
Integrated, Step-Down Switching Regulator  
General Description  
Benefits and Features  
High Power Density and Low Component Count  
The MAX20735 is a fully integrated, highly efficient  
switching regulator for applications operating from 4.5V to  
16V and requiring up to 40A maximum load. This single-  
chip regulator provides extremely compact, high-efficien-  
cy power-delivery solutions with high-precision output  
voltages and excellent transient response for networking,  
datacom, and telecom equipment.

and Output Capacitors

Fast Transient Response: Supports Up to 300A/μs  
Load Step Transients  
The IC offers a broad range of programmable features  
through capacitors and resistors connected to dedicated  
programming pins. Using this feature, the operation can  
be optimized for a specific application, reducing the  
component count- and/or setting-appropriate trade-offs  
between the regulator's performance and system cost.  
Ease of programming enables using the same design for  
multiple applications.  
Optimized Component Performance and Efficiency  
with Reduced Design-In Time  
Increased Power-Supply Reliability with System and  
IC Self-Protection Features  
Differential Remote Sense with Open-Circuit  
Detection  
• Hiccup Overcurrent Protection  
• Programmable Thermal Shutdown  
The MAX20735 includes protection capabilities. Positive  
and negative cycle-by-cycle overcurrent protection and  
overtemperature protection ensure a rugged design. Input  
undervoltage lockout shuts down the device to prevent  
operation when the input voltage is out of specification. A  
status pin provides an output signal to show that the out-  
put voltage is within range and the system is regulating.
