MaxLinear, Inc. Application Specific Microcontrollers SP6132HCU-L/TR

The SP6132HCU-L/TR is a synchronous step-down switching regulator controller designed for high efficiency, capable of operating with input voltages ranging from 3V to 28V. It features dual input capability and can deliver up to 30A output current. The device includes on-board NFET drivers with a 1.5,Ѷ sink and 2,Ѷ source resistance, ensuring effective power management. Key protection features include under-voltage lockout (UVLO) for both V_CC and V_IN, thermal shutdown, and short circuit protection with an auto-restart function. The controller operates at a fixed frequency of 300kHz and supports programmable soft start, which helps manage inrush current during startup. The SP6132H is housed in a compact 10-pin MSOP package, making it suitable for space-constrained applications. This product is particularly well-suited for applications in wireless base stations, automotive systems, industrial equipment, and power supplies, where high efficiency and reliability are critical.
