Product Overview
LTC®3805-5 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-circuits conditions. Soft-start can be programmed using an external capacitor and the soft-start capacitor also programs an automatic restart feature. Application includes automotive power supplies, telecom power supplies, isolated electronic equipment, auxiliary/housekeeping power supplies, power over Ethernet.
- Adjustable slope compensation
- Adjustable overcurrent protection with automatic restart
- Synchronizable to an external clock
- Programmable soft-start with one external capacitor
- Typical VCC turn-on voltage is 4.5V (VCC rising, TA = 25°C)
- Typical regulated feedback voltage is 0.800V (0°C ≤ TJ ≤ 85°C (E-Grade), TA = 25°C)
- Typical oscillator frequency is 70KHz (RFS = 350K, TA = 25°C)
- 10-lead plastic MSOP package
- Temperature rating range from -40°C to 125°C
