Product Overview: UCC38084PWR by Texas Instruments

The UCC38084PWR is a versatile and efficient PWM (Pulse Width Modulation) controller integrated circuit designed by Texas Instruments, a leader in semiconductor solutions. This device is part of the UCC3808x family of BiCMOS push-pull, high-speed, low-power PWM controllers. It is specifically engineered to drive a wide range of power supply applications, including isolated and non-isolated converters.

With its advanced features and compact design, the UCC38084PWR is optimized for off-line and DC-to-DC converter applications requiring a high level of efficiency and reliability. It operates at a fixed frequency that can be programmed by the user, providing flexibility in the design of the power supply. The controller supports a wide range of input voltages, making it suitable for various global power standards and applications.

The UCC38084PWR incorporates several protection features to ensure the safe operation of the power supply system. These include under-voltage lockout (UVLO) for both VCC and VREF, over-current protection (OCP), and a programmable soft-start function to minimize stress on the power supply during startup. Additionally, the device has a totem-pole output stage with high current drive capability for directly driving a power MOSFET or IGBT.

One of the key advantages of the UCC38084PWR is its low startup and operating currents, which contribute to the overall efficiency of the power supply. This low power consumption, coupled with the device's high performance, makes it an ideal choice for energy-sensitive applications.

The UCC38084PWR is available in a compact TSSOP-8 (Thin Shrink Small Outline Package) that is suitable for surface-mount technology (SMT), allowing for efficient use of PCB (Printed Circuit Board) space. This packaging, along with the chip's high level of integration, helps to reduce external component count, system complexity, and overall cost.

Whether you are designing a power supply for consumer electronics, industrial systems, or telecommunication equipment, the UCC38084PWR from Texas Instruments provides a reliable and high-performance solution that meets the stringent requirements of modern power management applications.
