The UCC2837NG4 application field covers AC and DC voltage control as well as high voltage current modes, and it is mainly used as a linear regulator controller for DC-DC converters and switches. Its wide range of features makes it popular in aircraft systems, automotive, industrial and a variety of other applications. The UCC2837NG4 also features a comprehensive on-chip diagnostic features suite that makes the details of system operation available for the end user and the manufacturer.

The principle of an UCC2837NG4 linear regulator controller is based on a field effect transistor (FET) device, also known as a transistor circuit generator. This type of circuit derives its power from a voltage source and feeds it to the main circuit by forming a feedback loop around the FET. The circuit acts as a voltage regulator and is guided by a set of reference values that are predefined in the software.

The output current of the UCC2837NG4 is monitored by programmable current limits and the output voltage is regulated with a pulse width modulator (PWM) controlled by an internal voltage regulator. The integrated limit circuitry also provides a manual reset function and an active low overtemperature protection (OTP) pin. All these features contribute to boost the system reliability.

The UCC2837NG4 linear regulator controller is also praised for its ability to detect abnormal input voltages, under-voltage and over-voltage lockouts. Also, through the use of additional logic, reference level programming and manual reset circuitry, the UCC2837NG4 broadens the regulator’s bandwidth and efficiency.
