MaxLinear, Inc. Voltage Regulators - DC DC Switching Regulators SP6652ER-L/TR

The SP6652ER-L/TR is a high-efficiency synchronous buck regulator designed for portable applications, capable of delivering up to 1A of output current. It operates at a fixed switching frequency of 1.4 MHz, which allows for the use of small inductors and ceramic output capacitors, making it suitable for space-constrained designs. The input voltage range is from 2.7V to 5.5V, and it features a maximum efficiency of 97%. Key features include a low shutdown current of 0.5µA, adjustable output voltage, and the ability to operate in a low dropout mode with 100% duty cycle. The device also incorporates soft-start functionality, thermal shutdown protection, and supports external clock synchronization. It is available in a compact 10-pin DFN package, compliant with RoHS standards. The SP6652ER-L/TR is ideal for applications such as mobile phones, PDAs, and USB devices, where efficient power management is critical.
