SP6125EK1-L [EXAR]

The SP6125 is a fixed frequency, voltage-mode, non-synchronous PWM controller optimized for minimum component count, small form factor, and cost effectiveness. It features internal Type-II compensation for use with electrolytic or tantalum output capacitors, a precision 0.6V reference, and programmable overcurrent protection based on high-side MOSFET RDS(ON) sensing. The device includes internal soft-start, 300kHz constant frequency operation, and a built-in high-current PMOS driver capable of 100% duty cycle operation. Available in a space-saving 6-pin TSOT package, it supports input voltages from 4.5V to 29V and includes UVLO, adjustable overcurrent protection, and 1% output voltage accuracy.
