IRS2526DS Mini8 Ballast Control IC
PRESS RELEASE
DATA SHEET
The IRS2526DS Mini8 is a compact fluorescent
lamp (CFL) ballast control IC that offers full
programmability, and a high degree of accuracy
and control for all lamp types. Available in an
8-pin SO-8 package, the new feature-rich IC
reduces component count, simplifies circuit
design and increases efficiency in a compact
footprint.

• Advantages
• The IRS2526DS features a 600V half-bridge control
  circuit working at 50 percent duty-cycle and
  variable frequency for driving the resonant mode
  lamp output circuit. The high accuracy
  oscillator is controlled by a single
  analog-to-frequency input pin used to set the
  different operating frequencies of the ballast.
• Complete fault protection circuitry is included
  for protection against such conditions as mains
  interrupt or brown-out, lamp non-strike, lamp
  filament failure and end-of-life.
• The device incorporates an internal frequency
  dither to reduce conducted EMI, ignition control
  to reduce inductor size, and end-of-life
  protection.
• The IRS2526DS IC differs greatly from alternative
  approaches because it packs additional features
  and functionality not found in other solutions in
  an 8 pin package. It is very easy to use and
  enables customers to significantly speed up their
  design time to develop a highly efficient
  electronic ballast lighting solution.
