The NJU7241F18-TE1 inverter works on the basis of regulating the output voltage by sensing the voltage drop across the transistor. The device consists of a voltage regulator, a reference voltage source, a temperature sensor and an I2C interface. It receives the voltage drop or error voltage, E, at its inverting input which is compared to the reference voltage. If the error voltage E is greater than the reference voltage, the output voltage increases to bring the error voltage to approximately zero and the device shuts down if the error voltage falls below the reference voltage.

In addition, the NJU7241F18-TE1 offers precise regulation over a wide range of output currents. The slope compensation can be adjusted to regulate the output voltage as the load current changes. The device also has a preload output soft-start for controlled output voltage start-up and a power-up and power-down sequencing function for output voltage ramp control. Moreover, the NMOS and PMOS low side power transistors can be configured in various configurations like boost, buck, SEPIC and flyback converters.
