概述

Description

MAX8557ETE+ is a Maxim Integrated power-management IC—specifically a dual, high‑efficiency synchronous DC‑DC regulator designed for compact, battery‑powered devices. It integrates switching MOSFETs and supports multiple regulated outputs from a single input, with features such as soft‑start, enable and sequencing, overcurrent/thermal protection, and power‑good signaling, in an extended‑temperature (ET) package. Typical uses include portable electronics, wearables, and IoT modules that require multiple rails from a single supply. For exact voltages, currents, and pinouts, refer to the latest MAX8557ETE+ datasheet.

Features

Here are the typical features you can expect from MAX8557ETE+ (high-level, concise):
- Synchronous buck regulator with integrated high- and low-side MOSFETs
- Wide input voltage range suitable for battery or power rails
- Adjustable output voltage via external feedback resistors (fixed versions available)
- High efficiency across load, with suitable operation in light-load/PFM modes
- Current-mode control for fast transient response
- Soft-start to prevent inrush and output overshoot
- Enable input for simple shutdown control
- Protections: undervoltage lockout, overcurrent/short-circuit protection, over-temperature shutdown
- Power-good/diagnostic indication (status flag)
- Extended temperature operation (ETE+) with Pb-free packaging
- Small footprint package suitable for compact designs
Note: For exact electrical specs (input range, jump to output voltage, switching frequency, current capability), consult the MAX8557ETE+ datasheet.

Package

MAX8557ETE+ is in a 28-pin TQFN (6×6 mm) package with an exposed pad; Pb-free version.

Pinout

Pin count: 8 pins.
Function: MAX8557ETE+ is an 8-pin DC-DC switching regulator (buck converter) with an integrated switching transistor. It converts a higher input voltage to a lower regulated output and requires external components (inductor, diode or synchronous switch, capacitors) and has an enable/shutdown input.

Manufacturer

MAX8557ETE+ is manufactured by Maxim Integrated (Maxim Integrated Products), a U.S. semiconductor company that designs and sells analog and mixed-signal integrated circuits. Maxim is now part of Analog Devices, Inc., a global semiconductor company.

Application

Applications: portable and embedded systems needing multiple voltage rails. Common areas include cellular/handheld devices, tablets, notebooks, DSP/FPGA/ASIC-based systems, wearables and portable media players; battery-powered industrial sensors; telecom/network equipment; and automotive electronics (infotainment and body electronics) where high efficiency and compact size are critical.
