NCP1581  
High Frequency Synchronous  
Step Down PWM Controller  
for Tracking Applications  
The NCP1581 controller IC is designed to provide a simple  
synchronous buck regulator for onboard DC to DC applications in a  
14pin SOIC. The NCP1581 is designed specifically for tracking  
applications by providing the track input.  
The NCP1581 operates at a fixed internal 400 kHz switching  
frequency allowing the use of small external components. The device  
features a programmable soft start set by an external capacitor,  
undervoltage lockout and output undervoltage detection that latches  
off the device when an output short is detected.
