UCC2895DW Information

Description

Here's a concise introduction to the UCC2895DW: The UCC2895DW is a BICMOS switching controller from Texas Instruments, designed for high-power and high-frequency applications. It features programmable output turn-on delay, adaptive delay set, bidirectional oscillator synchronization, and multi-mode control (voltage-mode, peak current-mode, or average current-mode). The device also provides programmable soft start/stop and chip disable via a single pin. The UCC2895DW supports efficient control of power delivery and is suitable for high-power applications such as power-factor correction circuits, resonant power supplies, and DC-DC converters. Its typical operating current at 500 kHz is only 5 mA, making it an energy-efficient option.

Features

According to the product information, some key features of the UCC2895DW are:

Programmable-output turnon delay
Adaptive delay set
Bidirectional oscillator synchronization
Voltage-mode, peak current-mode, or average current-mode control
Programmable soft start, soft stop, and chip disable via a single pin
0% to 100% duty-cycle control
7-MHz error amplifier
Operation up to 1 MHz
Low operating current (typical 5-mA at 500 kHz) and ultraslow standby current (150-µA during UVLO)

These features make it suitable for use in high-power, high-frequency applications such as PFC circuits, resonant power supplies, and DC-DC converters.

Package

The package type of UCC2895DW is SOIC-20 (Small Outline Integrated Circuit - 20 pins).

Manufacturer

The manufacturer of the UCC2895DW is Texas Instruments.

Applications

The UCC2895DW is commonly used in high-power, high-frequency applications such as power-factor correction (PFC) circuits, resonant power supplies, and DC-DC converters. It provides efficient control of power delivery, making it suitable for industrial, automotive, and telecommunications equipment.
