MAX17630  
4.5V to 36V, 1A, High-Efficiency,  
Synchronous Step-Down DC-DC Converter  
General Description  
Benefits and Features  
● Reduces External Components and Total Cost  
The MAX17630 is a high-efficiency, high-voltage,  
synchronous step-down DC-DC converter with integrated  
MOSFETs operating over an input-voltage range of 4.5V  
to 36V. It can deliver up to 1A current. The MAX17630 is  
available in three variants, MAX17630A, MAX17630B,  
and MAX17630C. The MAX17630A and MAX17630B  
are fixed 3.3V and fixed 5V output parts, respectively.  
The MAX17630C is an adjustable output voltage (0.9V  
• No Schottky - Synchronous Operation  
• Internal Compensation Components  
• All-Ceramic Capacitors, Compact Layout  
● Reduces Number of DC-DC Regulators to Stock  
• Wide 4.5V to 36V Input  
• Adjustable Output Voltage Range from  
0.9V Up to 90% of V  
IN  
up to 90% of V ) part. Built-in compensation across the  
IN  
• Delivers Up to 1A Over the Temperature Range  
• 400kHz to 2.2MHz Adjustable Frequency with  
External Clock Synchronization  
output-voltage range eliminates the need for external  
compensation components.  
The MAX17630 features peak-current-mode control  
architecture. The device can be operated in forced  
pulse-width modulation (PWM), pulse-frequency  
modulation (PFM), or discontinuous-conduction mode  
(DCM) to enable high efficiency under full-load and light-  
load conditions. The MAX17630 offers a low minimum on-  
time that allows high switching frequencies and a smaller  
solution size.  
• Available in a 16-Pin, 3mm x 3mm TQFN Package  
● Reduces Power Dissipation  
• Peak Efficiency of 95%  
• PFM and DCM Modes Enable Enhanced  
Light-Load Efficiency  
• Auxiliary Bootstrap Supply (EXTVCC) for  
Improved Efficiency  
• 2.8μA Shutdown Current  
The feedback-voltage regulation accuracy over -40°C to  
+125°C for the MAX17630A/MAX17630B/MAX17630C is  
±1.2%.The device is available in a 16-pin (3mm x 3mm)  
TQFN package. Simulation models are available.  
● Operates Reliably in Adverse Industrial Environments  
• Hiccup-Mode Overload Protection  
• Adjustable and Monotonic Startup with Prebiased  
Output Voltage  
• Built-in Output-Voltage Monitoring with RESET  
• Programmable EN/UVLO Threshold  
• Overtemperature Protection  
• High Industrial -40°C to +125°C Ambient  
Operating Temperature Range / -40°C to +150°C  
Junction Temperature Range  
Applications  
● Industrial Control Power Supplies  
● General-Purpose Point-of-Load  
● Distributed Supply Regulation  
● Base Station Power Supplies  
● Wall Transformer Regulation  
● High Voltage Single-Board Systems
