This is a LM5010 buck-boost regulator able to convert a positive input ranging from 10-50Vdc to -12V output. by Robert Bell @ www.edn.com Buck regulators find wide application as step-down regulators for converting large positive input voltages into a smaller positive output voltages. Figure 1 shows a simplified buck regulator that operates in continuous-conduction mode—that […]
