UCC3888D is an Industry Standard High-Performance Current Mode Controller from Texas Instruments. It is a high-performance, low-EMI off-line switcher optimized to reduce the component count and minimize board space. The device is ideal for a wide range of AC-DC, DC-DC, and AC-AC, mobile device chargers, and low power supplies. It is ideal for a variety of isolated and non-isolated power converter applications such as telecom, industrial, and consumer power supplies.
The UCC3888D is designed to operate with a minimum of external components in a wide range of applications, from light-loads to heavy-loads. It has an internal power rail converter circuit that allows the device to deliver high-efficiency performance in applications where high-power factors are required. The device is designed to operate with a wide range of power supplies and topologies, such as Buck, SEPIC, Forward, Flyback, and Push-Pull converters. It is designed to meet the demanding requirements of worldwide energy efficiency standards such as Level VI FPD-Efficiency and the Department of Energy’s efficiency standards. The device also offers protections against over-temperature, over-current, and open-loop faults.
The UCC3888D operates utilizing a current-mode control scheme with a voltage feedback loop; the input voltage is monitored by an internal voltage reference, and the current is monitored by an external low power resistor. The power MOSFET used in the application must be rated to handle the desired load current. The maximum operating frequency is set using an external resistor and an internal oscillator. The operating frequency can be set anywhere from 100 kHz to 600 kHz to optimize the efficiency of the power supply. The device output voltage can be adjusted by changing the programmed voltage ramp waveform.
The UCC3888D also provides several built-in safety protection features to protect the device and the application from fault conditions. These include cycle-by-cycle current limiting, over-voltage protection, over-temperature protection, and short circuit protection. It also provides a burst-mode operation to minimize the switching losses at light-loads.
Due to its flexibility, the UCC3888D is ideal for a wide range of power applications. It can be used in applications such as notebooks and desktops power supplies, lighting, solar inverters, communication systems, industrial control systems, metering systems, and many other off-line applications. The UCC3888D can also be used for DC-DC conversion applications, such as powering a digital logic circuit from a single battery cell, or powering multiple devices from a single battery cell. The device is also suitable for automotive, wireless, and medical applications. It is also ideal for high-density power applications such as mobile phone chargers and low-power supplies.
The UCC3888D is a high-performance current mode controller that offers high-performance efficiency and safety features, making it ideal for a wide range of power applications. Its flexible current-mode control scheme, low-power design, and integrated safety features make it suitable for a broad range of AC-DC, DC-DC, and AC-AC applications. Its burst-mode operation and high-performance features make it an optimal choice for power designs that require a high level of efficiency, low noise, and reliability.
