DC1247A

DC1247A demonstration circuit features the LT3582. This LT3582 is an I2C programmable boost and single inductor inverting DC/DC converter with OTP. It converts a 2.7V-5.5V source to two outputs, a positive and a negative. The positive output can be programmed from 3.2V to 12.775V at 25mV intervals and the negative from -1.2V to -13.95V at 50mV intervals, all via the QuickEval™ System. A DC590B is needed for evaluation of this demo board. The LT3582 features all integrated switches and feedback resistors, a low noise control scheme, positive output disconnect function, low quiescent current, built in softstart.

• Input supply range from 2.7 to 5.5V
• 10mV typ ripple pos and 40mV typ ripple neg at over inputs, outputs and loads
