UC3845ANG4 is a DC to DC switching controller manufactured by STMicroelectronics and distributed by STMicroelectronics – Hong Kong. It is used to control the voltage, current, and frequency of a system’s power supply. It is specifically tailored for use in DC to DC switching power supply and regulated power sources.

This controller is a monolithic integrated circuit device designed mainly for use in sequencing and controlling power stages for applications such as off-line or DC to DC converters, using either natural or forced air cooling. With the use of an external power pass element, the UC3845ANG4 can be used to build a wide variety of single ended reverse- or forward-conversion power sources.

The UC3845ANG4 is specifically built with advanced short circuit and thermal protection capabilities in order to protect components and equipment on the system\'s power lines. It is most commonly found in off-line power supplies, but can be used to control a wide variety of DC and AC power sources as well.

The UC3845ANG4 has a wide operating range, making it suitable for a variety of applications. It can operate between 7 V and 30 V at up to 2 A. This wide range of operation makes it suitable for automotive, industrial, and consumer applications. It also offers a very low input current, which allows it to be used in applications where power consumption is an important consideration.

The UC3845ANG4 has low content skip cycle and auto restart modes, which make it ideal for systems where timing is critical. It also supports current mode oscillator, phase-lock loop (PLL) and temperature compensation. Additionally, the device can be used to generate switching frequencies up to 500 kHz.

The working principle of this device can be summarized as follows. First, the UC3845ANG4 sets the operating parameters such as power output, current control, and switching frequency. It then adjusts the output voltage feedback to the controller through the voltage control input. Finally, the controller regulates the output voltage, current and frequency to the desired levels.
