FAN7930BCritical Conduction Mode (CrM) Power Factor Controller, Programmable OVP | Integrated Circuits (ICs) | 8 | Active | The FAN7930B is an active power factor correction (PFC) controller for boost PFC applications that operate in critical conduction mode (CRM). It uses a voltagemode PWM that compares an internal ramp signal with the error amplifier output to generate a MOSFET turn-off signal. Because the voltage-mode CRM PFC controller does not need rectified AC line voltage information, it saves the power loss of an input voltage sensing network necessary for a current-mode CRM PFC controller.FAN7930B provides over-voltage protection, openfeedback protection, over-current protection, inputvoltage- absent detection, and under-voltage lockout protection. The additional OVP pin can be used to shut down the boost power stage when output voltage exceeds OVP level due to the resistors that are connected at INV pin are damaged. The FAN7930B can be disabled if the INV pin voltage is lower than 0.45V and the operating current decreases to a very low level. Using a new variable on-time control method, THD is lower than the conventional CRM boost PFC ICs. |

FAN80601.2MHz, 1A Synchronous Step-Down DC/DC Converter | Integrated Circuits (ICs) | 2 | Active | The FAN8060 is a highly efficient, monolithic, currentmode, step-down synchronous regulator. It can provide 1A continuous current from 2.5V to 5.5V input voltage. The output voltage can be adjusted from 1.2V up to the input voltage with an external voltage divider. External compensation and soft-start allow for design optimization and flexibility. High-frequency operation allows for all-ceramic solutions and small footprints. In addition, a user-selectable current limit provides protection against output overload and short circuit. FAN8060 features pulse skipping to achieve higher efficiency during light load operation. 100% duty cycle capability enables power solutions to extend the drop out voltage. Provision for external synchronization allows users to minimize input capacitors and manage EMI in solutions. FAN8060 is available in a green, low profile, 10-Lead 3x3mm MLP package. |

FAN8303Step-Down DC-DC Regulator, Non-Synchronous, 2 A, 23 V | Power Management (PMIC) | 1 | Obsolete | The FAN8303 is a monolithic, non-synchronous, stepdown (buck) regulator with internal power MOSFETs. It achieves 2 A continuous output current over a wide input supply range with excellent load and line regulation. Current-mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The regulator draws less than 40 µA shutdown current. FAN8303 requires a minimum number of readily available standard external components.External compensation, enable, and programmable soft-start features allow design optimization and flexibility. Cycle-by-cycle current limit, frequency foldback, and thermal shutdown provide protection against shorted outputs. |
