IRS2538DSPBF Datasheet Magnetic Replacement Ballast

Manufacturer: International Rectifier (now Infineon)

Overview: IRS2538DSPBF Magnetic Replacement Ballast IC.

General Description

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

The IC includes a novel single-stage circuit topology and control method to achieve high power factor and low THD without a PFC stage or any electrolytic capacitors.

A single high-voltage pin senses the halfbridge voltage to perform necessary protection functions.

Key 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.
