MC33025DW Description

Short technical summary and product information.

The MC33025DW from ON Semiconductor is a high-speed, fixed-frequency, double-ended pulse width modulator controller optimized for high-frequency operation. It is suitable for Off-Line and DC-to-DC converter applications, offering a cost-effective solution with minimal external components.

 

Key features include a wide bandwidth error amplifier, dual high current totem pole outputs, and a fully-latched logic with double pulse suppression. The controller supports voltage or current mode operation up to 1.0 MHz and has a maximum duty cycle of 45%, which is externally adjustable. It also includes protective features such as input and reference undervoltage lockouts with hysteresis and cycle-by-cycle current limiting.

 

This device is available in a 16-SOIC package and is designed for surface mount applications. It operates over a temperature range of -40°C to 105°C (TA). The MC33025DW is Pb-free and Halogen-free, complying with RoHS standards.

 

It is functionally similar to the UC3825 and is ideal for designers seeking a flexible and efficient PWM controller for power supply designs.
