The Texas Instruments UC3836N is a high-performance current mode pulse width modulator controller that has been designed to deliver precise electrical control in a variety of power conversion applications. This integrated circuit is particularly well-suited for switch-mode power supplies, DC to DC converters, and as a driver for power MOSFETs in a broad range of engineering projects.

Key Features

• Current Mode Operation: The UC3836N operates in current mode, offering improved transient response and simplified loop compensation over voltage mode PWMs.
• High-Frequency Capability: This device is capable of operating at frequencies up to 500kHz, making it ideal for applications requiring high switching frequencies for smaller, more efficient designs.
• Low Startup and Operating Current: The low startup current (typically 0.5mA) and operating current (typically 8mA) minimize power losses and improve efficiency.
• Programmable Dead Time: It features programmable dead time, which provides design flexibility and helps prevent transformer saturation and MOSFET cross-conduction.
• Under-Voltage Lockout (UVLO): UVLO ensures that the controller remains off until the supply voltage reaches an operational level, protecting the circuit components.

Applications

The UC3836N is versatile and can be used in a variety of applications, including:

• DC to DC Converters
• Offline Power Supplies
• Forward and Flyback Converters
• Motor Control Circuits
• Class D Power Amplifiers
