Product Description: UC3842 DIP PWM Controller
The UC3842 is a high-performance pulse-width modulation (PWM) controller designed for off-line and DC-DC converter applications. Housed in an 8-pin DIP package, it is optimized for use in switch-mode power supplies (SMPS) and provides efficient power management solutions.
Key Features
- Current-Mode PWM Control: Allows for precise control of the output voltage and current.
- Wide Operating Voltage Range: Operates effectively from 12V to 28V.
- High Switching Frequency: Capable of switching frequencies up to 500 kHz, enabling compact designs.
- Integrated Functions: Includes features such as soft-start, over-voltage protection, and under-voltage lockout to enhance reliability.
- High Current Output: Provides a high-current totem-pole output capable of sourcing or sinking up to 200 mA.
Specifications
- Maximum Duty Cycle: Can achieve a maximum duty cycle of approximately 100%.
- Operating Supply Current: Typically around 25 mA, ensuring low power consumption during operation.
- Temperature Range: Designed to operate within a temperature range of 0?C to 70?C.
Applications
The UC3842 is commonly used in:
- Switching Power Supplies: Ideal for both isolated and non-isolated power supply designs.
- DC-DC Converters: Efficiently converts one DC voltage level to another.
- Battery Chargers: Manages charging cycles and optimizes battery performance.
