The UC3867N from Texas Instruments is a DC DC switching controller designed for applications requiring flexible power management. It supports multiple topologies including Full-Bridge, Half-Bridge, and Push-Pull configurations, making it adaptable to various design needs.
This controller operates within a supply voltage range of 7V to 22V, with a maximum duty cycle of 100%. It features a soft start control to manage power-up sequences smoothly. The device provides two outputs and one output phase, functioning as a transistor driver for positive output configurations.
Designed for through-hole mounting, the UC3867N comes in a standard 16-PDIP package. Its operating temperature range is from 0°C to 70°C (TA), suitable for a wide array of environmental conditions. The frequency range for switching is between 50kHz and 500kHz, allowing for efficient power conversion.
Key specifications include its ability to perform Step-Up/Step-Down functions, a non-synchronous rectifier, and no clock sync capability. This makes the UC3867N a robust component for power supply designs.
