MC34025P Description

Short technical summary and product information.

The MC34025P from ON Semiconductor is a high-speed, fixed-frequency, double-ended pulse width modulator controller optimized for high-frequency operation. It is 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 device supports voltage or current mode operation up to 1.0 MHz and has a maximum duty cycle of 45%, which is externally adjustable. Protective features include input and reference undervoltage lockouts, cycle-by-cycle current limiting, and a latch for single pulse metering.

 

This controller is suitable for applications requiring precise control and protection. It is available in a 16-PDIP package and supports Through Hole mounting. The operating voltage range is 8.4V to 30V, with an operating temperature range of 0°C to 70°C.

 

The MC34025P is Pb-Free, Halogen Free/BFR Free, and RoHS Compliant.
