UC3844BVNG Description

Short technical summary and product information.

The UC3844BVNG from ON Semiconductor is a fixed-frequency, current-mode controller optimized for off-line and DC-DC converter applications. It features an oscillator, a temperature-compensated reference, a high-gain error amplifier, and a high-current totem pole output, making it suitable for driving power MOSFETs.

 

This controller operates with a voltage range of 10V to 36V and supports a maximum duty cycle of 48%. Its frequency can reach up to 500kHz, enabling efficient power conversion. The device includes essential protective features such as undervoltage lockout with hysteresis and cycle-by-cycle current limiting.

 

The UC3844BVNG is available in an 8-pin PDIP package, designed for through-hole mounting. Its operating temperature range is -40°C to 105°C (TA). This component is well-suited for applications requiring precise frequency control and efficient current management.
