DESCRIPTION  
The SP6126 is a PWM controlled step down (buck) voltage mode regulator with VIN feedforward and  
internal Type-II compensation. It operates from 4.5V to 29V making is suitable for 5V, 12V, and 24V  
applications. By using a PMOS driver, this device is capable of operating at 100% duty cycle. The  
high side driver is designed to drive the gate 5V below VIN. The programmable overcurrent  
protection is based on high-side MOSFET’s ON resistance sensing and allows setting the  
overcurrent protection value up to 300mV threshold (measured from VIN-LX). The SP6126 is  
available in a space-saving 6-pin TSOT package making it the smallest controller available capable  
of operating from 24VDC supplies.
