ON Semiconductor MC33025DWR Product Overview

The MC33025DWR is a high-performance, dual-output PWM (Pulse Width Modulation) controller integrated circuit manufactured by ON Semiconductor. It is designed to cater to a wide range of power supply applications, including but not limited to, switch-mode power supplies, DC-DC converters, and motor control circuits. This versatile component is a key solution for engineers looking to achieve efficient power management and precise control in their electronic designs.

Key Features

• Dual Output Drive Stages: The MC33025DWR features two independent output drive stages that can sink or source up to 200 mA. This capability allows for direct drive of the power stage's MOSFET or IGBT, facilitating robust power control.
• Wide Operating Range: It operates over a broad voltage range, accommodating supply voltages from 10 V to 30 V, which makes it highly adaptable to various power systems.
• High Frequency Operation: The device supports high-frequency operation up to 1 MHz, which enables the design of power supplies with smaller components, reduced noise, and improved efficiency.
• Programmable Dead Time: With programmable dead time control, designers can fine-tune the overlap of the output stages to optimize efficiency and prevent cross-conduction.
• Protection Features: The MC33025DWR is equipped with an array of protection features, including under-voltage lockout, thermal shutdown, and a latch-off mechanism for overcurrent conditions, ensuring the reliability and safety of the power supply system.
