The ON Semiconductor UC2845BNG is a high-performance fixed-frequency current mode controller. It is designed for off-line and DC-DC converter applications, offering a cost-effective solution with minimal external components. This integrated circuit features an oscillator, a temperature-compensated reference, a high-gain error amplifier, a current-sensing comparator, and a high-current totem pole output.
Key electrical specifications include an operating voltage range of 7.6V to 30V and a maximum duty cycle of 48%. The controller can operate at frequencies up to 500kHz, with an oscillator frequency guaranteed at 250kHz. Output deadtimes are adjustable from 50% to 70%.
Protective features include input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and a latch for single pulse metering. The UC2845BNG is available in an 8-pin dual-in-line (PDIP) package and is suitable for through-hole mounting.
This device is well-suited for applications requiring precise frequency control and efficient power conversion. Its robust design and integrated features make it a versatile choice for various power supply designs.
