Description
The LM2586 is part of the LM258x family of SIMPLE SWITCHER® boost regulators from TexasInstruments. The internal NPN is capable of handling a voltage of 65V and has a current limit of 4A. Themaximum input voltage that the device can handle is 40V. Thus this device makes a good candidate forwide VIN solutions. The design shown here is created for a typical input of -5V and output of -12V at 1Aload current, with a common ground between input and output. But it can handle an input voltage range of-5V to -24V. The following sections will talk about the operation
