UC3846DWTR

.The UC3846DWTR is an integrated current-mode pulse-width modulation (PWM) controller designed to provide access to simple, flexible, and easy-to-use increased power conversion performance. It features programmable frequency range, operating power supply range, under-voltage lockout, cycle-by-cycle current limit protection, and feature-rich protection. This device contains advanced functions that allow it to reduce EMI by up to 15dB. It is suitable for both transformer-based and capacitor-input power supply designs and can sustain peak current load up to 80A. The improved frequency jittering feature of the UC3846DWTR enhances efficiency and enables optimized operation in mobile applications, as well as in wide range of AC/DC, DC/DC converter topologies.
