sc2434 Semtech Corporation, sc2434 Datasheet - Page 17

• Manufacturer Part Number: sc2434
• Description: Sc2434 Triphase Current Mode Controller With Power Good
• Manufacturer: Semtech Corporation

Fig. 13 - Transient response and the test condition:
The transient response for a maximum load step changes (10A to 60A) is shown in Fig. 14, where one can see that
accurate drooping will help to reduce the amount of output capacitance needed. Please notice that using more
multilayer ceramic capacitors for better high frequency decoupling can reduce the narrow voltage spikes.
