ICE3RBR4765JZ

概要

Off-line SMPS Current Mode Controller IC with integrated 650V CoolMOS™ and start-up cell in DIP-7 package. It has more robust design and can work to -40°C. The outstanding performance includes BiCMOS technology, active burst mode, built-in frequency jitter, soft gate driving, propagation delay compensation, built-in soft start time, built-in blanking time and extendable blanking time for over load protection, external auto-restart enable feature,etc.

特長

  • 650V avalanche rugged CoolMOS™ with built-in Start-up Cell
  • Active burst mode for lowest standby power
  • Fast load jump response in active burst mode
  • 65kHz internally fixed switching frequency
  • Auto restart protection mode for overload, open
    loop, V CC under voltage, over temperature & over voltage
  • Built-in soft start
  • Built-in blanking window with extendable blanking time for short duration high current
  • External auto-restart enable pin
  • Max duty cycle 75%
  • Overall tolerance of current limiting < ±5%
  • Internal PWM Leading Edge Blanking
  • BiCMOS technology provide wide V CC range
  • Built-in Frequency jitter and soft driving for low EMI

利点

  • Lowest standby power requirements <50mW
  • Low operating temperature down to -40°C
  • Auto restart protection for overload, over temperature, over voltage
  • Wide VCC range
  • Soft driving for low EMI
