MaxLinear, Inc. DC DC Switching Controllers SP6128AHY-L/TR

The SP6128AHY-L/TR is a low voltage, synchronous step-down PWM controller designed for efficient DC-DC power conversion. It operates from a single supply voltage of 3V to 5.5V and is optimized for applications requiring output currents between 2A and 10A. The device features a high efficiency of over 95%, making it suitable for low voltage applications where space and cost are critical. This controller operates at a fixed frequency of 300kHz, allowing for the use of smaller inductors and minimizing PCB space. It includes an internal soft start circuit, fast transient response, and a precise 0.8V reference voltage, enabling low output voltage configurations. The SP6128AHY-L/TR also incorporates programmable output voltage and overcurrent thresholds, along with loss-less current limit protection through high-side R_DS(ON) sensing. Packaged in a 14-pin TSSOP, the device has a quiescent current of 500¬µA and only 30¬µA in shutdown mode. It supports various applications, including DSPs, microprocessors, and industrial control systems. The operating temperature range is -40¬8C to +105¬8C, and it is available in lead-free packaging.
