MC34025DWR2G Description

Short technical summary and product information.

The MC34025DWR2G 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 fully-latched logic with double pulse suppression. It supports voltage or current mode operation up to 1.0 MHz and has a maximum duty cycle of 45%, which is externally adjustable. The device operates within a supply voltage range of 8.4V to 30V and has a startup voltage of 9.2V.

 

Protective features include input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and a latch for single pulse metering. The MC34025DWR2G is available in a 16-SOIC package and operates at ambient temperatures between 0°C and 70°C.

 

This controller is designed for applications requiring precise control and high-speed switching, such as power supplies and converters. Its integrated features simplify design and reduce component count.
