The UCC3809-2 is an economy primary side controller designed for off-line and isolated DC-to-DC fixed frequency current mode switching power supplies. It operates with a maximum frequency of 1 MHz and features a low startup current of 100 ¬µA. The device includes user-programmable soft start, maximum duty cycle, and undervoltage lockout (UVLO) with specific thresholds for turn-on and turn-off. The UCC3809-2 can source up to 0.4 A and sink up to 0.8 A, making it suitable for driving N-channel MOSFETs. It is available in an 8-pin SOIC package and is optimized for applications where board space is limited. The operating temperature range for this part is 0¬8C to 70¬8C.
