DESCRIPTION

The SP6127 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 VIN, making it suitable for 5V, 12V and 24V applications. By using a PMOS driver, this device is capable of operating at 100 duty cycle. The highside driver is designed to drive the gate 5V below VIN. The programmable overcurrent protection is based on the high-side MOSFET’s ON resistance sensing and allows setting the overcurrent protection value up to 300mV threshold (measured between VIN-LX). The SP6127 is available in a space-saving 6-pin TSOT package making it the smallest controller available capable of operating from 24VDC supplies.
