Description
Product Overview
DC2793A demonstration circuit is a high VIN no-opto synchronous flyback converter featuring the LT®8316. The demo board outputs 5V and maintains tight regulation with a load current from 70mA to 7A. It is optimized to operate over a wide 140V to 450V DC input voltage range. Output voltage accuracy stays within ±5% over the entire input voltage and load range. On the secondary side, the LT8309 synchronous rectifier driver senses the synchronous MOSFET drain-to-source voltage to determine its turn-on period. By replacing the diode rectifier with an N-Channel MOSFET, the efficiency and thermal performance is greatly improved. DC2793A features an option to turn on standby mode by simply changing the position of a jumper from �DIS� to �EN�. Standby mode reduces the minimum switching frequency to 220Hz for ultralow quiescent power consumption.
- 4.75V to 5.25V output voltage range at IOUT = 70mA to 7A
- 7A maximum output current
- 80mVP-P output voltage AC ripple (peak-to-peak) at VIN = 140V, IOUT = 7A
- 45KHz typical switching frequency at VIN = 140V, IOUT = 7A
- 89% efficiency at VIN = 140V, IOUT = 7A
