Transformer Driver for  
MAX253  
Isolated RS-485 Interface  
General Description  
Benefits and Features  
The MAX253 monolithic oscillator/power-driver is  
specifically designed to provide isolated power for an  
isolated RS-485 or RS-232 data interface. The device  
drives a center-tapped transformer primary from a 5V  
or 3.3V DC power supply. The secondary can be  
wound to provide any isolated voltage needed at power  
levels up to 1W.  
• Simple Power-Supply Transformer Driver Design for  
Isolated RS-485/RS-232 Data-Interface Applications  
• Single 5V or 3.3V Supply  
• Low-Current Shutdown Mode: 0.4µA  
• Pin-Selectable Frequency: 350kHz or 200kHz  
®
• 8-Pin DIP, SO, and µMAX Packages Take Minimal  
Board Space  
The MAX253 consists of a CMOS oscillator driving a  
pair of N-channel power switches. The oscillator runs  
at double the output frequency, driving a toggle flip-  
flop to ensure 50% duty cycle to each of the switches.  
Internal delays are arranged to ensure break-before-  
make action between the two switches.
