HIGH_VOLTAG_E_POSITIVE_SWITCHING

Published:2009/7/14 5:02:00 Author:May | From:SeekIC

Designed for operation from supply voltages above 40-V maximum rating of LM305 regulator. Output is +5 V at up to l0 A. Circuit uses fraction of input voltage as determined by R9 and zener, with Q2 providing voltage isolation between regulator and Unitrode PIC626 hybrid power switch.- Switching Regulator Design Guide, Unitrode, Watertown, MA, 1974, U-68A, p 9.
