ON UC3843BD1G

升压，升压/降压反激，升压7.6V ~ 30V

Overview

The UC3843BD1G is a high performance fixed frequency Current Mode Controller specifically designed for OFF-line and DC-DC converter applications. This integrated circuit features a trimmed oscillator for precise duty cycle control, a temperature compensated reference and high gain error amplifier, current sensing comparator and a high current totem pole output ideally suited for driving a power MOSFET. Also includes protective features consisting of input and reference under-voltage lockouts each with hysteresis, cycle-by-cycle current limiting, programmable output dead-time and a latch for single pulse metering.
