Description
UC2572N Description
The UC2572N is a negative output flyback pulse width modulator which converts a positive input voltage to a regulated negative output voltage.
The chip is optimized for use in a single inductor negative flyback switching converter employing an external PMOS switch.
The block diagram consists of a precision reference, an error amplifier configured for voltage mode operation, an oscillator, a PWM comparator with latching logic, and a 0.5A peak gate driver.  UC2572N
