Self-driven synchronous rectified boost converter with inrush current protection using bidirectional normally on device

摘要: A boost converter in which the conventional diode is replaced by a bidirectional normally conducting semiconductor switch. The circuit may be implemented so switch self-driven connecting low voltage Schottky between first gate-source terminal pair. An inrush current protection function provided utilizing second pair to turn on and off independent of operation response predetermined excessive load conditions. use connected gate source terminals, an RC return rail for power output transistor with externally controlled control bias according current.
