Features & Applications

The MC33025 series are high speed, fixed frequency, double−ended pulse width modulator controllers optimized for high frequency operation. They are specifically designed for Off−Line and DC−to−DC converter applications offering the designer a cost effective solution with minimal external components. These integrated circuits feature an oscillator, a temperature compensated reference, a wide bandwidth error amplifier, a high speed current sensing comparator, steering flip−flop, and dual high current totem pole outputs ideally suited for driving power MOSFETs.

Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, cycle−by−cycle current limiting, and a latch for single pulse metering. The flexibility of this series allows it to be easily configured for either current mode or voltage mode control.

Key Features:

  • 50 ns Propagation Delay to Outputs
  • Dual High Current Totem Pole Outputs
  • Wide Bandwidth Error Amplifier
  • Fully−Latched Logic with Double Pulse Suppression
  • Latching PWM for Cycle−By−Cycle Current Limiting
  • Soft−Start Control with Latched Overcurrent Reset
  • Input Undervoltage Lockout with Hysteresis
  • Low Startup Current (500 A Typ)
  • Internally Trimmed Reference with Undervoltage Lockout
  • 45% Maximum Duty Cycle (Externally Adjustable)
  • Precision Trimmed Oscillator
  • Voltage or Current Mode Operation to 1.0 MHz
  • Functionally Similar to the UC3825
  • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
