The UC3844BVN from On Semiconductor is a high-performance fixed-frequency current mode controller. It is engineered for off-line and DC-DC converter applications, providing a cost-effective solution requiring minimal external components. This integrated circuit includes an oscillator, a temperature-compensated reference, a high-gain error amplifier, a current sensing comparator, and a high-current totem pole output suitable for driving a power MOSFET.
Key features include cycle-by-cycle current limiting, input and reference undervoltage lockouts with hysteresis, and a latch for single pulse metering. The output deadtime can be programmed from 50% to 70%. The device operates over a voltage range of 10V to 36V with an operating temperature range of -40°C to 105°C (TA). It supports topologies such as Boost and Flyback and can operate at frequencies up to 500kHz.
The UC3844BVN is available in an 8-pin PDIP package for through-hole mounting. It is designed for applications requiring precise frequency control and efficient power management.
