FAN7382 − Half Bridge Gate Driver

The FAN7382, a monolithic half-bridge gate driver IC, can drive MOSFETs and IGBTs that operate up to +600V. Fairchild's high-voltage process and common-mode noise canceling technique provides stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level shift circuit allows high-side gate driver operation up to VS = -9.8 V (typ.) for VBS = 15V. The input logic level is compatible with standard TTL-series logic gates. UVLO circuits for both channels prevent malfunction when VCC and VBS are lower than the specified threshold voltage. Output drivers typically source/sink 350mA/650mA, respectively, which is suitable for fluorescent lamp ballasts, PDP scan drivers, motor controls, etc.

A High Power Factor Flyback with Constant-Current Output for LED Lighting Applications This article explains the principles of AC/DC converters in flyback topology having a high power factor input and a constant current output. The most commonly used mode of operation for this purpose is boundary conduction mode (BCM). The basics of this mode are developed and its drawbacks are made clear. A simple method for improving power factor is introduced and explained in detail. Operating in DCM mode improves power factor and THD while reducing the peak drain voltage. A quick design example is given and the special issues of driving high power LEDs are explained.
