DESCRIPTION
The SP6126 is a PWM controlled step down (buck) voltage mode regulator with V IN 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 V IN . 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 V IN -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.
