Product Overview
LTC3805-5 is a current mode DC/DC controller designed to drive an N-channel MOSFET in flyback, boost and SEPIC converter applications. Operating frequency and slope compensation can be programmed by external resistors. Programmable overcurrent sensing protects the converter from overload and short-circuit conditions. Soft-start can be programmed using an external capacitor and the soft-start capacitor also programs an automatic restart feature. It 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 device can be powered from a high VIN through a resistor or it can be powered directly from a low impedance DC voltage from 4.7V to 8.8V. It is used in application such as automotive power supplies, telecom power supplies, isolated electronic equipment, auxiliary/housekeeping power supplies, power over Ethernet etc.
- VIN and VOUT limited only by external components
- 4.5V undervoltage lockout threshold
- Adjustable slope compensation
- Synchronizable to an external clock
- ±1.5% reference accuracy
- RUN pin with precision threshold and adjustable hysteresis
- Peak current sense voltage is 100mV typ at (TA = 25°C, VCC = 5V)
- Oscillator frequency is 70KHz typical at (RFS = 350K, TA = 25°C, VCC = 5V)
- Operating temperature is -40°C to 150°C
- Package style is 10-lead plastic MSOP
