The UC2844N from Unitrode is a versatile current-mode Pulse Width Modulation (PWM) controller IC. It is optimized for use in both off-line and DC-to-DC converter applications, requiring a minimal number of external components for implementation. This controller features a wide operating voltage range from 10V to 30V and can operate at frequencies up to 500kHz.
Key electrical characteristics include a maximum duty cycle of 48%, a low start-up current of less than 1mA, and an undervoltage lockout with hysteresis. The output stage is a high-current totem-pole design suitable for driving N-channel MOSFETs. The device also incorporates automatic feedforward compensation and pulse-by-pulse current limiting for enhanced control and protection.
Packaged in an 8-pin DIP (Dual In-line Package) with through-hole mounting, the UC2844N is specified for an operating temperature range of -40°C to 85°C. Its design makes it suitable for various switching regulator applications, including boost and flyback topologies.
