XRP6657IHBTRF – MAXLINEAR

The XRP6657IHBTRF is a high-efficiency, synchronous step-down (buck) DC-DC regulator integrated circuit manufactured by MaxLinear. It features an adjustable output voltage, configurable via external resistor divider, and is capable of delivering up to 1.5A of continuous output current. The device operates with a wide input voltage range, typically from 4.5V to 18V, accommodating various power supply rails. The XRP6657IHBTRF employs a constant-frequency PWM control architecture to minimize output voltage ripple and ensure stable operation across varying load conditions. Protection features include over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown. It is packaged in a space-saving 6-pin DFN (Dual Flat No-Lead) package with a thermal pad for enhanced heat dissipation, facilitating compact PCB designs. The switching frequency is internally set, optimizing efficiency and minimizing external component size.
