5BR4780BZ - Fixed-frequency 800V / 950V CoolSET

Datasheet Summary

Description

The ICE5xRxxxxxZ is the fifth-generation of fixed-frequency integrated power IC (CoolSET™) optimized for offline switch-mode power supplies in cascode configuration.

The CoolSET™ package contains two separate chips.

One is the controller chip and the other is the 800 V / 950 V CoolMOS™ chip.

Features

  • Integrated 800 V / 950 V avalanche rugged CoolMOS™.
  • Enhanced Active Burst mode with selectable entry and exit standby power.
  • Digital frequency reduction for better overall system efficiency.
  • Fast startup achieved with cascode configuration.
  • DCM and CCM operation with slope compensation.
  • Frequency jitter and soft gate driving for low EMI.
  • Built-in digital soft start.
  • Integrated error amplifier to support direct feedback in non-isolated flyback and buck top.
