Descripción general

Description

FAN53611AUC18X is a multi-rail power-management IC from the FAN53xx family (Fairchild/ON Semiconductor). It integrates switching regulators and LDOs to generate the required rails for portable devices, with programmable voltages and sequencing. The device is controlled by a digital interface (I2C/SPI-like) and includes protections such as overcurrent, short-circuit, undervoltage, and thermal shutdown. The AUC18X suffix denotes a specific packaging/revision variant (e.g., an 18-pin package). Typical applications include smartphones, tablets, wearables, and other battery-powered electronics. If you need exact electrical specs or the datasheet, I can summarize or pull the key parameters once you share the document or allow a specific query.

Features

Here are typical features of the FAN53611AUC18X family:
- Multi-rail synchronous buck regulator with integrated high/low-side MOSFETs
- Wide input voltage range suitable for notebook/embedded applications
- Adjustable output rails via external feedback; proper sequencing/tracking between rails
- High efficiency (synchronous rectification) and good transient response
- Current-mode control with fast response to load changes
- Soft-start and programmable ramp/limit for safe power-up
- Enable control and Power-Good/status signals
- Robust protections: overcurrent/short-circuit, overvoltage, undervoltage, thermal shutdown
- Fault handling with safe hiccup behavior on faults
- Small 18-pin AUC package (with exposed pad for heat dissipation), suited for compact PMIC implementations
Note: for exact pinout, rail count, voltage ranges, and electrical specs, please consult the official datasheet.

Package

FAN53611AUC18X is in an 18-pin QFN (leadless) package with an exposed pad (typical 4×4 mm body).
