MC33025P Description

Short technical summary and product information.

The MC33025P from ON Semiconductor is a high-speed, fixed-frequency, double-ended pulse width modulator controller. It is optimized for high-frequency operation and is suitable for Off-Line and DC-to-DC converter applications, providing a cost-effective solution with minimal external components.

 

Key features include a wide bandwidth error amplifier, dual high current totem pole outputs ideal for driving power MOSFETs, and a propagation delay to outputs of 50 ns. The device operates with a voltage range of 8.4V to 30V and supports operation up to 1.0 MHz. It includes protective features such as input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and a latch for single pulse metering.

 

The MC33025P can be configured for either current mode or voltage mode control. It has a maximum duty cycle of 45%, which is externally adjustable. The controller is available in a 16-PDIP through-hole package, with an operating temperature range of -40°C to 105°C (TA).

 

This device is Pb-Free and Halogen Free, and is RoHS compliant. It is functionally similar to the UC3825.
