The E-UC2842BN from STMicroelectronics is a high-performance, fixed-frequency current-mode PWM controller that has been engineered for a wide range of power supply applications. This integrated circuit is designed to offer low startup and operating current, which makes it an excellent choice for power-efficient designs.

Key Features

• Optimized for Off-line and DC-to-DC Converters: The E-UC2842BN is ideal for use in switch-mode power supplies (SMPS), enabling efficient conversion of electrical power in both off-line and DC-to-DC contexts.
• Low Startup Current: With a startup current of just 0.5mA, this controller helps to minimize power consumption during the initial power-up phase.
• Automatic Feed Forward Compensation: This feature allows the controller to compensate for varying input voltages, ensuring stable operation across different power levels.
• Pulse-by-Pulse Current Limiting: Enhanced protection is provided by the controller's ability to limit the current in each pulse, preventing damage to the power supply components.
• Under-Voltage Lockout with Hysteresis: The E-UC2842BN includes an under-voltage lockout feature with hysteresis to ensure that the controller operates only when the input voltage is within a safe range.
• Double Pulse Suppression: This safety feature prevents the controller from generating double pulses, which can lead to power supply instability.

Applications

The versatile nature of the E-UC2842BN makes it suitable for a variety of applications, including:

• Off-line power supplies
