UC1825B-SP - Radiation Hardened High-Speed PWM Controller

General Description

The UC1825B-SP PWM control device is optimized for high-frequency switched mode power supply applications.

Particular care was given to minimizing propagation delays through the comparators and logic circuitry while maximizing bandwidth and slew rate of the error amplifier.

Key Features

  • QML-V qualified, SMD 5962-8768106.
  • 5962R8768106VYC:.
  • Radiation hardness assurance (RHA) up to 100-krad(Si) total ionizing dose (TID) 1.
  • Compatible with voltage- or current-mode topologies.
  • Practical operation switching frequencies to 1 MHz.
  • 50-ns propagation delay-to-output.
  • High-current dual totem pole outputs (2-A peak).
  • Wide bandwidth error amplifier.
  • Fully latched logic with double-pulse suppression.
  • P.
