Anpec Electronics APW7279

The APW7279 integrates with two high-performance step- • Current Mode Step-up Regulator (LCD bias) up converter and two charge pump controllers for TFT- - 1MHz Fixed Operating Frequency LCD and Backlight applications. Both the two step-up - Fast Transient Response regulators are a current-mode, fixed-frequency PWM - 18V/700mA ,1.5Ω Internal N-MOS switching regulator. The 1.0MHz switching frequency al- • Positive & Negative Charge Pump Driver for VGH, lows the usage of low-profile inductors and ceramic ca- V GL • Current Mode Step-up Regulator (LED BL) pacitors to minimize the thickness of LCD panel designs.
