The UC3844BNG from ON Semiconductor is a versatile, high-performance current mode controller suitable for both Off-Line and DC-DC converter applications. It offers a cost-effective solution with minimal external components.
Key electrical specifications include an operating voltage range of 10V to 36V and a maximum duty cycle of 48%. The controller supports switching frequencies up to 500kHz, with a guaranteed oscillator frequency of 250 kHz. It features automatic feed-forward compensation and latching PWM for cycle-by-cycle current limiting.
This device is available in an 8-pin PDIP package designed for through-hole mounting. The operating temperature range is from 0°C to 70°C (TA). Protective features include input and reference undervoltage lockouts with hysteresis, and cycle-by-cycle current limiting.
The UC3844BNG is designed for applications requiring precise frequency control and adjustable output deadtimes from 50% to 70%. Its high current totem pole output is ideal for driving power MOSFETs.
