Tổng Quan Sản Phẩm
LTC®3805 is a current mode controller for flyback DC/DC converters designed to drive an N-channel MOSFET in high input and output voltage converter applications. Operating frequency and slope compensation can be programmed by external resistors. Programmable overcurrent sensing protects the converter from short-circuits. Soft-start can be programmed using an external capacitor and the soft-start capacitor also programs an automatic restart feature. This provides ±1.5% output voltage accuracy and consumes only 360µA of quiescent current during normal operation and only 40µA during micropower start-up. Using a 9.5V internal shunt regulator, this can be powered from a high VIN through a resistor or it can be powered directly from a low impedance DC voltage of 9V or less. Typical applications are telecom power supplies, 42V and 12V automotive power supplies, isolated electronic equipment.
- VIN and VOUT limited only by external components

- Current mode operation for excellent line and load transient response
- RUN pin with precision threshold and adjustable hysteresis
- Programmable soft-start with one external capacitor
- Input DC supply current is 360µA (normal operation (fOSC=200KHz))
- 10-lead plastic MSOP package
- Temperature rating range from –40°C to 125°C
