Electronic circuits form a mostly invisible part of the world we live in today. These circuits are present in microchips or just "chips", which combine the latest advances in performance, intelligence and, efficiency. Hundreds or thousands of these chips are integrated into each of the millions and billions of electronic devices people across the globe interact with every day. It is in this unseen realm that STMicroelectronics creates the sparks that animate the products we use at any given moment. Our technology is found everywhere microelectronics makes a positive contribution to people's lives. Chips from ST embedding the most advanced innovations are an essential part of products as diverse as cars and key fobs, giant factory machines and data center power supplies, washing machines and hard disks, and smartphones and toothbrushes. We help our customers make these devices more intelligent, more energy efficient, more connected, safer and more secure.

Description

The UC3842A , UC3843A series of high performance fixed frequency current mode controllers are specifically designed for off line and DC to DC converter UC3842A , UC3843A, UC3844A, UC3845A. SLUS224F SEPTEMBER 1994 REVISED OCTOBER 2017. UCx84xA Current-Mode PWM Controller. 1. The UTC UC3842A /3843A provide the necessary functions to implement off-line or DC to DC fixed frequency current mode , controlled switching circuits with utilizing UC3842 control. CURRENT-MODE CONTROL. Figure 1 shows the two- loop current-mode control system in a typical buck regulator application. A. for noise concerns. output ripple: if ripple pollutes feedback, tail chasing can occur. crossover frequency rolloff is mandatory, e.g. in PFC circuits.
