The ON Semiconductor MC34025DW is a high-speed, fixed-frequency, double-ended pulse width modulator controller optimized for high-frequency operation. It is specifically designed for Off-Line and DC-to-DC converter applications, offering a cost-effective solution with minimal external components.
Key features include a 50 ns propagation delay to outputs, dual high current totem pole outputs, and a wide bandwidth error amplifier. The controller supports voltage or current mode operation up to 1.0 MHz and has a maximum duty cycle of 45%. It includes protective features such as input and reference undervoltage lockouts, cycle-by-cycle current limiting, and a latch for single pulse metering.
This device is available in a 16-SOIC package and is designed for surface mount applications. It operates within a supply voltage range of 8.4V to 30V and has an operating temperature range of 0°C to 70°C (TA). The MC34025DW is functionally similar to the UC3825.
It is suitable for applications requiring precise control of power conversion, such as power supplies and converters. The integrated features simplify design and reduce component count.
