The UC2842BDG is a fixed frequency, current mode pulse width modulator (PWM) controller manufactured by Texas Instruments. It is an integrated circuit used for regulating the voltage at a given point by managing the energy transfer from a DC power source to an output device. This type of controller is also known as a DC-DC switching controller, and has applications in a variety of consumer electronics, automotive, and power management, and industrial solutions.

The UC2842BDG is a high performance and versatile pulse width modulator (PWM) controller optimized for regulating the voltage in a given system. It includes a fixed frequency oscillator and a control circuit which can be configured to provide an adjustable duty cycle. This makes it ideal for high current, multiple output solutions or solutions with a wide input voltage range. The UC2842BDG is designed to operate over a temperature range between -40°C and +125°C.

The UC2842BDG output switch can be configured to handle a maximum current of 13A, making it suitable for a wide range of applications. This device features a programmable under voltage lockout level, making it suitable for systems that require high input sensitivity. Additionally, this device features a programmable soft start capability that helps reduce inrush currents at system turn-on.

The UC2842BDG control circuit includes a ramp generator and an internal error amplifier that regulates the output voltage. The ramp generator produces a triangular wave form that is compared with the voltage divider voltage. The voltage difference between the two is amplified, and the amplified error voltage is then used to modify the duty cycle of the output switch.

The UC2842BDG features an input voltage range of 4.5V to 40V, making it suitable for a wide range of applications. Moreover, the device includes a Synchronous-Rectifier (SR) output with a local Extremely Low Gate Charge (ELGCS) which helps reduce switching losses and output voltage drop. Additionally, the UC2842BDG includes a dedicated output for monitoring current and a dedicated output for resetting system if the current sense signal exceeds a programmable threshold.

The UC2842BDG is an excellent PWM controller for multiple output solutions, as it is capable of operating over a wide input voltage range and provides plenty of adjustability and protection features. This device is highly suitable for a variety of applications, ranging from consumer electronics and automotive, to power management and industrial solutions.
