... A1, the oscillator is turned off. A low signal on the shutdown pin gates off the oscillator, overriding A1. With SHUTDOWN low, quiescent current remains at 360 A. TM Burst Mode is a trademark of Linear Technology Corporation W U are unsuitable for use in any switching regulator applica- tion. Although they are rated at 1A, the switching time of a 1N4001 is in the range. At best, efficiency will be severely compromised if this diode is used ...
