Synchronous Step-Down DC-DC Converter  
General Description  
Benefits and Features  
●ꢀ EliminatesꢀExternalꢀComponentsꢀandꢀReducesꢀTotalꢀ  
Cost  
The MAX17502 high-efficiency, high-voltage, synchronous  
step-down DC-DC converter with integrated MOSFETs  
operates over a 4.5V to 60V input voltage range. This  
device is offered in a fixed 3.3V , 5V or adjustable output

• Internal Compensation and Feedback Divider for  
3.3V and 5V Fixed Outputs  
• All-Ceramic Capacitors, Ultra-Compact Layout  
voltage (0.9V to 92%V ) while delivering up to 1A of  
IN  
current. The output voltage is accurate to within ±1.7%  
over -40°C to +125°C. The MAX17502 is available in  
compact TDFN and TSSOP packages. Simulation models  
are available.  
●ꢀ ReducesꢀNumberꢀofꢀDC-DCꢀRegulatorsꢀtoꢀStock  
• Wideꢀ4.5Vꢀtoꢀ60VꢀInputꢀVoltageꢀRange  
The device features peak-current-mode control with  
pulse-width modulation (PWM) and operates with fixed  
switching frequency at any load. The low-resistance,  
on-chip MOSFETs ensure high efficiency at full load and  
simplify the layout.  
• 0.9V to 92%V Adjustable Output Voltage  
• Delivers up to 1A  
• 600kHzꢀandꢀ300kHzꢀSwitchingꢀFrequencyꢀOptions  
• Available in a 10-Pin, 3mm x 2mm TDFN and  
14-Pin, 5mm x 4.4mm TSSOP Packages  
IN  
A programmable soft-start feature allows users to reduce  
input inrush current. The device also incorporates an  
output enable/undervoltage lockout pin (EN/UVLO) that  
allows the user to turn on the part at the desired input-  
voltage level. An open-drain RESET pin provides a  
delayed power-good signal to the system upon achieving  
successful regulation of the output voltage.
