CYPAS212A132LQXQTXUMA1

DC DC Switching Controllers Overview

The CYPAS212A132LQXQTXUMA1 is a secondary-side Active Clamp Flyback (ACF) controller designed for USB-C chargers supporting up to 28V Extended Power Range (EPR). It integrates an EZ-PD Protocol Controller compliant with USB PD 3.0 and PPS specifications. The device operates within a switching frequency range of 20 kHz to 300 kHz and supports output voltages from 3.3 V to 28 V. It features a maximum duty cycle of 55% and functions within an operating supply voltage range of 3.3 V to 30 V. The component is housed in a 32-pin QFN package (5x5 mm) and is rated for industrial temperatures between -40°C and +105°C.

• GaN-based fast charger designs requiring integrated protocol control
• High-density power supplies for mobile devices and laptops

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'LQXQT' against the manufacturer's current ordering guide, as suffixes often denote tape-and-reel packaging or moisture sensitivity levels. Confirm RoHS compliance status directly with Infineon documentation prior to procurement. Ensure the design accounts for the specified humidity sensitivity classification during storage and reflow soldering processes.

DC DC Switching Controllers Selection Notes

Select this component when designing USB-C EPR chargers requiring a compact solution that combines power regulation and protocol negotiation in a single IC. It is suitable for applications prioritizing efficiency through ACF topology over traditional flyback designs. Consider the 32-QFN footprint constraints and thermal requirements for high-power density implementations.

DC DC Switching Controllers Part Context

This part belongs to Infineon's CYPAS series, which targets the growing market for USB Type-C and GaN-based power adapters. It complements other variants like the CYPAS213 by offering specific integration for secondary-side control, reducing component count compared to discrete controller and protocol chip solutions.

DC DC Switching Controllers Replacement Considerations

Direct pin-to-pin replacements are limited due to the integrated EZ-PD functionality. Evaluate alternative CYPAS series members only if they match the required USB PD version and EPR voltage support. Verify compatibility with existing PCB layouts and firmware configurations if migrating between similar controllers.
