LM3477 Description
LM3477/LM3477A High Efficiency High-Side N-Channel Controller for Switching Regulator June 2002 LM3477/LM3477A High Efficiency High-Side N-Channel C.LM3477 Features
* include internal soft-start and output over voltage protection. The internal soft-start reduces inrush current. Over voltage protection is a safety feature to ensure that the output voltage stays within regulation. The LM3477A is similar to the LM3477. The primary difference between the two is the pLM3477 Applications
* The LM3477/A uses a high switching frequency of 500kHz to reduce the overall solution size. Current-mode control requires only a single resistor and capacitor for frequency compensation. The current mode architecture also yields superior line and load regulation and cycle-by-cycle current limiting.
