The MC33023DW from ON Semiconductor is a high-performance, dual-output, pulse width modulation (PWM) controller designed for a wide array of power conversion and motor control applications. This versatile component is engineered to offer precision control of power delivery, ensuring efficient operation in systems requiring DC to DC conversion, AC to DC conversion, or motor control.

Key Features

• Wide Operating Range: The MC33023DW operates at a frequency range up to 1 MHz, allowing for compact power supply designs with smaller external components.
• High Current Totem Pole Output: Capable of driving large MOSFETs or IGBTs directly, this feature simplifies the design and reduces component count.
• Undervoltage Lockout: This safety feature ensures the controller only operates when the supply voltage is within an acceptable range, preventing potential damage to the system.
• Adjustable Dead-Time: The dead-time can be set precisely to optimize system efficiency and minimize cross-conduction losses.
• Double Pulse Suppression: Ensures reliable operation by preventing erroneous pulses that could lead to power stage damage.

Applications

The MC33023DW is ideal for various applications, including:

• Switch Mode Power Supplies (SMPS)
• DC-DC Converters
• AC-DC Power Supplies
• Uninterruptible Power Supplies (UPS)
• Brushless DC Motor Controllers
