UCC28730QDRQ1 +BOM

Zero-power standby PSR flyback controller for automotive

UCC28730QDRQ1 Information

Description

The Texas Instruments UCC28730QDRQ1 is a flyback converter IC designed for automotive and industrial applications. It's an AC-DC switching converter that operates at 90 kHz, making it suitable for LED lighting, motor drives, and battery chargers. This device is AEC-Q100 qualified, ensuring its reliability in harsh environments. The UCC28730QDRQ1 features primary-side regulation (PSR), eliminating the need for an optocoupler. It also offers zero-power standby consumption, making it energy-efficient. The IC has a wide input voltage range and can operate at temperatures from -40°C to 125°C. This device is ideal for applications that require high efficiency, robust performance, and reliability in harsh environments. Its compact SOIC-7 package makes it suitable for space-constrained designs.

Features

According to the product information, the UCC28730QDRQ1 features:

  • AEC-Q100 qualified for automotive applications
  • Functional safety-capable with documentation available
  • Zero-power standby consumption (<5mW)
  • Primary-side regulation (PSR) eliminates opto-coupler
  • ±5% voltage and current regulation across line and load
  • 700-V start-up switch with 30-V minimum start-up voltage
  • 83-kHz maximum switching frequency for low standby power charger designs
  • Resonant-ring valley-switching operation for highest overall efficiency
  • Frequency-dither to ease EMI compliance
  • Clamped gate-drive output for MOSFET
  • Over-voltage, low-line, and over-current protection functions
  • Programmable cable compensation

These features make it suitable for automotive and industrial applications such as power factor correction (PFC), isolated flyback converters, LED lighting, motor drives, and battery chargers.

Package

The package type of the UCC28730QDRQ1 is SOIC (D)-7, which is a 7-pin Small Outline Integrated Circuit package.

Manufacturer

The manufacturer of the UCC28730QDRQ1 is Texas Instruments (TI). TI is a leading global semiconductor company that designs, manufactures, and tests semiconductors, including analog and embedded processing chips. With a focus on innovation and customer satisfaction, TI excels in providing products for a wide range of applications, from automotive and industrial to consumer electronics and medical devices.

Applications

According to the product description, the UCC28730QDRQ1 is commonly used in automotive and industrial applications for power factor correction (PFC) and isolated flyback converters. It's ideal for LED lighting, motor drives, and battery chargers due to its high efficiency and robust performance in harsh environments.

Equivalent

After analyzing the product information, I found that there isn't a direct equivalent product from Texas Instruments (TI). However, TI does offer other flyback converters with similar features, such as the UCC28722 and UCC28732. These devices are also designed for automotive and industrial applications, but may not have all the specific features of the UCC28730QDRQ1. Other manufacturers like STMicroelectronics, ON Semiconductor, and Power Integrations also offer flyback converters with similar functions, but it's recommended to consult their respective datasheets for a detailed comparison.
