Overview of UCC2809P-2
The UCC2809P-2 is a member of the UCC3809 family, designed for use in off-line and isolated DC-to-DC fixed frequency current mode switching power supplies. With its integrated control and drive circuitry, this BCDMOS economy low power IC requires minimal external parts, making it a cost-effective solution for power supply applications. The device features undervoltage lockout with a startup current of less than 100µA, a user-accessible voltage reference, latched operation logic, and a PWM comparator, among other internally implemented circuits. Its totem pole output stage is capable of sinking or sourcing peak current and is ideal for driving N-Channel MOSFETs
