Economy Primary Side Controller

The UCC3809 family of BCDMOS economy low power integrated circuits contains all the control and drive circuitry required for off-line and isolated DC-to-DC fixed frequency current mode switching power supplies with minimal external parts count. Internally implemented circuits include undervoltage lockout featuring startup current less than 100A, a user accessible Voltage Reference Logic to ensure latched operation, a PWM Comparator and a totem pole output stage to sink or source peak current. The output stage, suitable for driving N-Channel MOSFETs is low in the off state.
Oscillator frequency and maximum duty cycle are programmed with two resistors and a capacitor. The UCC3809 family also features full cycle soft start.
The family has UVLO thresholds and hysteresis levels for off-line and DC-to-DC systems as shown in the table to the left.
The UCC3809 and the UCC2809 are offered in the 8 pin SOIC (D), PDIP (N), TSSOP (PW), and MSOP (P) packages. The small TSSOP and MSOP packages make the device ideal for applications where board space and height are at a premium.
