A low-current, negative high-voltage is required to bias sensors in advanced driver assistance systems, ultrasonic transducers for sonar applications and communications equipment. Flyback, Cuk and inverting buck-boost converters are all possible solutions but are penalized by bulky transformers (flyback and Cuk) or limited in their maximum negative voltage by the controller’s input-voltage rating (inverting buck-boost).

An accelerometer is a sensor that measures acceleration. These sensors can be used in shock and vibration measurements.

The location of the control accelerometer is a key decision when vibration tests take place, as it can roughly affect the results in this kind of tests with small components. Commonly, the control accelerometer is placed in one...
