FAN5235QSC Description

Short technical summary and product information.

The FAN5235QSC is a high-efficiency, high-precision DC/DC controller from On Semiconductor, suitable for notebook converters and portable instruments. It operates with an input voltage range of 5.4V to 24V and provides multiple output voltages including 3.3V, 5V, and an adjustable 12V boost output. The controller utilizes both input and output voltage feedback for fast and stable loop response.

 

Key features include synchronous rectification, an internal reference with ±1% precision, and an internally set 300kHz ±15% oscillator. The device supports 5V and 3.3V main outputs that switch out of phase to minimize input ripple current. It also offers 5V-ALWAYS and 3.3V-ALWAYS outputs for continuous power. The FAN5235QSC is available in a 24-pin QSOP package and a 24-pin TSSOP package, designed for surface mount.

 

Applications for the FAN5235QSC include notebook PCs, PDAs, and hand-held portable instruments. Its design incorporates features like input UVLO, output OVP of buck converters, and precision current limit options for the main outputs, along with a Power Good voltage monitor.
