High Voltage Power Supply


Posted on Feb 11, 2013

The TPS61040 is a highly integrated, low power, boost converter capable of delivering output voltages up to 28 V. However, using a coupled inductor enables the TPS61040 to be used in applications where higher voltages are required. Output voltages up to 75 V are achieved using this technique.



In the typical application circuit for the TPS61040, the maximum allowable voltage on the SW pin limits the output voltage to 28 V. Substituting the inductor with a 1 to 5 transformer allows the TPS61040 to deliver output voltages over 75 V. In this con
