SP6120 is a low voltage, synchronous buck controller optimized for single supply 3V-5.5V applications. It features high efficiency, selectable discontinuous or continuous conduction mode, fast transient response, accurate reference voltage and frequency.
The SP6120 is a fixed‑frequency, voltage‑mode PWM controller designed for 3 V‑5.5 V input supplies and targeted at 2 A‑10 A DC‑DC step‑down converters. It features Sipex’s AnyFET™ technology, allowing either PFET or NFET high‑side switches, selectable discontinuous or continuous conduction modes, and a rail‑to‑rail 1 % reference.
Key specifications include a typical oscillator frequency of 300 kHz, a quiescent current of less than 1 mA, and a 16‑pin TSSOP package. The device provides programmable output voltage, soft‑start, and over‑current protection, making it suitable for battery‑powered and bus‑powered applications.
