MAX17536  
4.5V to 60V, 4A, High-Efficiency, Synchronous  
Step-Down DC-DC Converter  
with Internal Compensation  
General Description  
Benefits and Features  
The MAX17536 high-efficiency, high-voltage, synchronous  
step-down DC-DC converter with integrated high-side  
MOSFET operates over a 4.5V to 60V input. The  
converter can deliver up to 4A and generates output

• No Schottky-Synchronous Operation  
• Internal Compensation for Any Output Voltage  
• Built-In Soft-Start  
voltages from 0.9V up to 0.9 x V . The feedback (FB)

voltage is accurate to within ±1.4% over -40°C to +125°C.  
ReducesꢀNumberꢀofꢀDC-DCꢀRegulatorsꢀtoꢀStock  
• Wide 4.5V to 60V Input  
The MAX17536 uses peak current-mode control. The  
device can be operated in the pulse-width modulation  
(PWM), pulse-frequency modulation (PFM), and  
discontinuous-conduction mode (DCM) control schemes.
