The ISL6551IR is a voltage regulator controller integrated circuit (IC) that provides a versatile and efficient solution for step-up and step-down voltage regulation.
The LM2621MM/NOPB is a versatile integrated circuit (IC) from Texas Instruments specifically designed for step-up and step-up/step-down voltage conversion applications.
Its protection features such as over-current, over-temperature, reverse-polarity and under-voltage lockout (UVLO) make it a reliable and safe option among other IC regulators.
