说明
- Demonstration circuit DC459A features the LT1946 and LT1946A boost DC/DC converter with 1.5A switch and built in soft start. The circuit is designed to convert 5V input to 12V output at 400mA of load current. The triple output TFT LCD bias supply (lower circuit) uses 2.7MHz LT1946A in thermally enhanced MS8E package. The circuit is designed to convert 3.3V input to 8V at 350mA, 23Vat 5mA, and -8V at 10mA TFT LCD bias outputs
