MAX8557ETE+

MAX8557ETE+ is a high-efficiency synchronous buck regulator from Maxim Integrated (now Analog Devices) used to generate a regulated low-voltage rail from a higher input in portable electronics. It integrates the high- and low-side MOSFETs and the control circuitry, delivering adjustable output with good transient response and high efficiency. Typical features include an enable input, current-mode control, soft-start, and protections such as overcurrent and thermal shutdown, all in a compact package. Applications include smartphones, tablets, wearables, and other battery-powered devices needing a stable rail. For design, connect VIN, SW, GND, EN, and FB per the datasheet, and select the inductor and input/output capacitors accordingly. Exact electrical specs (input range, output voltage, current capability, switching frequency) vary by variant; consult the MAX8557ETE+ datasheet for precise details and package options.

Pin count: 28 pins (in the MAX8557ETE+ package variants).
Function: A dual synchronous buck regulator/power-management IC with two DC-DC converter outputs, plus the usual control/feedback, enable, input, ground, and status pins. (Exact pinout varies by package; please consult the datasheet for the specific variant you have.)

- Manufacturer: Maxim Integrated (now part of Analog Devices, Inc.)
