MaxLinear, Inc. Voltage Regulators - DC DC Switching Regulators SP6651AER-L/TR

The SP6651AER-L/TR is a high-efficiency synchronous buck regulator designed for portable applications, capable of delivering up to 800mA output current. It operates within an input voltage range of 2.7V to 5.5V and can adjust the output voltage down to 1.0V. The device features an ultra-low quiescent current of 20µA, which increases to 80µA in dropout conditions, making it suitable for battery-powered devices. With a peak inductor current limit of 1.25A and a 100% duty ratio for low dropout operation, the SP6651AER-L/TR ensures efficient power management as the input voltage approaches the output voltage. It includes protective features such as over-temperature protection, programmable under-voltage lockout (UVLO), and logic shutdown control. The regulator is packaged in a compact 10-pin DFN format, measuring 3mm x 3mm, and is available in lead-free options. This product is ideal for applications such as PDAs, digital still cameras, MP3 players, and USB devices, where space and efficiency are critical.
