MaxLinear SP7661

Wide Input Voltage Range 3A, 600kHz, Buck Regulator


TopologyBuck Converter
Input voltage9.6-22 V
Output 13.3 V / 3 A
IC revisionN


The SP7661 is a synchronous step-down switching regulator optimized for high efficiency. The part is designed for use with a single 4.75V to 22V single supply or 3V to 22V input if an external Vcc is provided. The SP7661 provides a fully integrated buck regulator solution using a fixed 600kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown, output current limit and short circuit protection. The SP7661 is available in the space saving DFN package.
