The UC3572N from Texas Instruments is a negative output flyback pulse width modulator. This IC is optimized for single inductor flyback switching converters that produce a regulated negative output voltage from a positive input voltage. It features a precision reference, error amplifier, oscillator, PWM comparator, and a 0.5A peak gate driver.
Key electrical characteristics include an operating voltage range of 4.75V to 30V and an oscillator frequency of 100kHz. The device also incorporates an undervoltage lockout (UVLO) circuit and pulse-by-pulse current limiting. A low sleep mode current of 50µA makes it suitable for battery-powered applications.
The UC3572N is housed in an 8-PDIP package and is designed for through-hole mounting. Its operating temperature range is 0°C to 70°C (TA). The device supports a maximum duty cycle of 92% and is configured for negative output.
This component is suitable for various power management applications requiring negative voltage generation through a flyback topology. Its integrated features simplify the design of efficient switching converters.
