Introducing the UCC2813PW-3G4 Low-Power BiCMOS Current-Mode PWM Controller from Texas Instruments

Enhance your power management solutions with the cutting-edge UCC2813PW-3G4, a robust and reliable current-mode pulse width modulation (PWM) controller from the trusted semiconductor manufacturer, Texas Instruments (TI). This device is designed to offer precise power delivery and improved efficiency for a wide range of applications, including but not limited to, power supplies, DC-DC converters, and battery management systems.

The UCC2813PW-3G4 is part of TI's UCC2813x family of BiCMOS PWM controllers, which are well-known for their low startup and operating currents. This particular model operates with a 3.3V reference, making it ideal for systems that require a lower voltage operation. The device is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package), providing a compact footprint suitable for space-constrained applications.

Key features of the UCC2813PW-3G4 include:

• Low Startup and Operating Currents: This feature ensures minimal power loss during operation, contributing to the overall efficiency of the system.
• Current Mode Control: Offers fast response to load changes and inherent protection against short-circuits, enhancing the reliability and performance of your power system.
• Frequency Oscillation: The device operates at a fixed frequency of 100kHz, which provides a predictable noise spectrum and simplifies the design of noise filters.
• Trimmed Oscillator Discharge Current: This ensures consistent and accurate duty cycle limits to prevent overdriving of the external power switch.
• Under-Voltage Lockout (UVLO): Both startup and operating UVLO thresholds are programmable, safeguarding the device and the power system from operating under sub-optimal voltage conditions.

Whether you're developing power supplies for consumer electronics, telecommunications, or industrial systems, the UCC2813PW-3G4 offers a high-performance solution that is both cost-effective and energy-efficient. Its advanced features and reliable operation make it a go-to choice for engineers looking to optimize their power management designs.
