High speed circuits demand careful attention to layout and component placement. To assure proper performance of the UC1824 follow these rules: 1. Use a ground plane. 2. Damp or clamp parasitic inductive kick energy from the gate of driven MOSFETs. Do not allow the output pins to ring below ground. A series gate resistor or a shunt 1-A Schottky diode at the output pin serves this purpose. 3. Bypass VCC, VC, and VREF. Use 0.1-μF monolithic ceramic capacitors with low equivalent series inductance. Allow less than 1 cm of total lead length for each capacitor between the bypassed pin and the ground plane. 4. Treat the timing capacitor, CT, like a bypass capacitor. 5 Submit Documentation Feedback |
