APW7276 Description
The APW7276 integrates with a high-performance stepup converter, two charge pump controllers and one high current operational amplifiers for TFT-LCD applications. The main step-up regulator is a current-mode, fixed-frequency PWM switching regulator. The 1.5MHz switching frequency allows the usage of low-profile inductors and ceramic capacitors to minimize the thickness of LCD panel designs.The charge pump...
