Functional Block Diagram. Pin Functional Description DRAIN (D) Pin: The power MOSFET drain connection provides internal operating current for both startup and steady-state operation. BYPASS (BP) Pin: A 0.1 μF external bypass capacitor for the internally generated 5.8 V supply is connected to this pin. FEEDBACK (FB) Pin: During normal operation, switching of the power MOSFET is controlled by this pin. MOSFET switching is disabled when a current greater than 70 μA flows into this pin. SOURCE (S) Pin: This pin is the power MOSFET source connection. It is also the ground reference for the BYPASS and FEEDBACK pins. LinkSwitch-LP Functional Description LinkSwitch-LP comprises a 700 V power MOSFET switch with a power supply controller on the same die. Unlike conventional PWM (pulse width modulation) controllers, it uses a simple ON/OFF control to regulate the output voltage. The controller consists of an oscillator, feedback (sense and logic) circuit, 5.8 Vregulator, BYPASS pin undervoltage circuit, over-temperature Figure 3. Pin Configuration. protection, frequency jittering, current limit circuit, and leading edge blanking. Oscillator The typical oscillator frequency is internally set to an average of 66/83/100 kHz for the LNK562, 563 & 564 respectively. Two signals are generated from the oscillator: the maximum duty cycle signal (DC MAX) and the clock signal that indicates the beginning of each switching cycle.
