Automotive 9V - 19.5Vin to 5V at 1A with 60V Transient Protection and 1.7MHz Switching Frequency

The LT3682 is a 1A monolithic buck switching regulator that accepts input voltages from 3.6V to 36V and transients up to 60V. It features an adjustable and synchronizable switching frequency from 250kHz to 2.2MHz. It also has the ability to monitor the current flowing through the external catch diode, thus providing an extra level of protection against output fault conditions over the entire operating frequency range, regardless of input voltage. These features, together with its typical 75μA no load quiescent current makes the LT3682 the right choice in high frequency automotive and battery powered applications.
