It is designed for automotive and industrial applications requiring high reliability and efficient power management.","working_principle":"The DC-DC converter uses current mode PWM control. The error amplifier compares the output feedback with an internal reference. The PWM comparator controls the on-time of the internal power MOSFET. Current mode control provides fast transient response and cycle-by-cycle current limiting.","pin_description":"
