Product overview

5962P8680603VEA at a glance

5962P8680603VEA is a 16-pin ceramic dual-in-line current-mode PWM controller for radiation-aware, high-reliability power conversion. The UC1846-SP architecture combines programmable pulse-by-pulse current limiting, dual totem-pole outputs, push-pull symmetry correction, undervoltage lockout, soft start and synchronization. The orderable identity is tied to DLA drawing 5962-86806 and a military −55 °C to +125 °C operating range.

Key features

Verified device capabilities

  • The controller implements fixed-frequency current-mode regulation with programmable pulse-by-pulse current limiting.
  • Dual totem-pole outputs and automatic symmetry correction support push-pull converter arrangements.
  • Undervoltage lockout, soft-start capability, a shutdown terminal and double-pulse suppression are integrated.
  • The exact military PIN maps to TI's UC1846J-RHA ordering family under DLA drawing 5962-86806.

Applications

Where the device is used

  • TI lists satellite buses and payloads among the intended applications for this radiation-hardened controller.
  • The current-mode architecture supports regulated power stages used in space launch systems.
  • Supported topologies include flyback, forward, push-pull, half-bridge and full-bridge implementations.
  • Synchronization and parallel-operation capability support modular converter designs.
