IRS2538DSPBF - Magnetic Replacement Ballast

Datasheet Summary

Description

This IC takes full advantage of IR’s patented ballast and high-voltage technologies to realize a simple, highperformance magnetic ballast replacement solution.

Features

  • Ballast control plus half-bridge driver in one IC.
  • Single-stage topology (no PFC stage required).
  • High PF and low THD.
  • Preheat, ignition and running lamp modes.
  • Closed-loop lamp current control.
  • Half-bridge NZVS protection.
  • Adaptive dead-time.
  • Lamp insert auto-restart.
  • Internal bootstrap MOSFET.
  • Micro-power start-up current.
  • 15.6V internal zener clamp on VCC.
  • Excellent ESD and latch immunity.
  • RoHS compliant.
  • 8-pin SO8 package.
