The UC3572N from Unitrode is a negative output flyback pulse width modulator. This integrated circuit is optimized for single inductor flyback switching converters that produce a regulated negative output voltage from a positive input voltage. It features an operating voltage range of 4.75V to 30V and a typical operating frequency of 100kHz.
Key internal blocks include a precision reference, an error amplifier, an oscillator, a PWM comparator, and a 0.5A peak gate driver. The device incorporates an undervoltage lockout (UVLO) circuit to ensure sufficient input voltage before switching begins, and a pulse-by-pulse current limit for protection. It also includes a sleep comparator that reduces supply current to 50µA, making it suitable for battery-powered applications.
The UC3572N is housed in an 8-PDIP package and is designed for through-hole mounting. It operates within a temperature range of 0°C to 70°C.
This controller is suitable for applications requiring a negative voltage output, such as in power supplies for specific electronic devices or subsystems where negative rail voltages are necessary.
