U3525U pwm equivalent, regulating pwm.
NOR logic, giving a LOW output for an OFF state. An under-voltage lockout circuitry, which keeps the outputs off and the soft-start capacitor discharged for sub-normal in.
The UTC U3525U is a pulse width modulator IC and designed for switching power supplies application to improve performance and reduce external parts usage.
A shutdown terminal controls both the soft-start circuitry and the output stages, providing in.
