Abstract
This paper proposes a high-performance pulse-width modulation (PWM) AC/DC controller, which can drive a high-voltage (HV) 650-V power metal-oxide-semiconductor field-effect Transistor (MOSFET) in typical applications of adapters in portable electronic devices. In order to reduce the standby power consumption and improve the response speed in the start-up state, an improved under voltage lockout (UVLO) circuit without a voltage reference source or comparator is adopted. The AC/DC controller is fabricated using a 40-V 0.8-μm one-poly two-metal (1P2M) CMOS process, and it only occupies 1410 × 730 μm2. A 12 V/2 A flyback topology for quick-charge application is illustrated as the test circuit, which is currently one of the most advanced power adapters in use. Test values show that the turn-on and the turn-off threshold voltages are 19.318 and 8.01 V, respectively. A high hysteresis voltage of 11.308 V causes the value of the power-charging capacitor to decrease to as low as 1 μF to reduce production cost. In addition, the start-up current of 2.3 μA is extremely small, and is attributed to a reduction in the system's standby power consumption. The final test results of the overall system are proven to meet the Energy Star VI standard. The controller has already been mass produced for industrial applications.-
