This user guide supports the FAN9611/12 400W evaluation board for interleaved boundary-conduction-mode power-factor-corrected supply. It should be used in conjunction with the FAN9611/12 datasheet as well as the Fairchild application note AN-6086 Design Considerations for Interleaved Boundary-Conduction Mode PFC Using FAN9611 / FAN9612. Although marked FAN9612, the evaluation board is functionally identical to the FAN9611.

The FPF200X EVM is an Evaluation Module for Fairchild Semiconductor FPF2000 smart load switches family. The FPF200X family is a 0.7 Ω PMOS load switches with controlled turn-on, fast turn-off, and current limit. The current Limit is guaranteed for 50mA and 100mA with 1.8V to 5.5V range of input voltage. The Evaluation Module has test points for convenient access to the all pins and jumpers for setting the various load conditions along with switches for toggling the ON/OFF and configuring the ON pin polarity. The Board can be presented as a stand alone unit with a 1.8-5.5V battery for testing the basic functions.

AN6016 is an application note about the LCD backlight inverter drive IC (FAN7311). The IC provides a highly efficient CCFL backlight power supply for notebook computers and other portable applications. It features small size, high efficiency, and low cost. The FAN7311 integrates various circuit blocks including feedback-controlled PWM driver stage, soft start, open lamp regulation, and UVLO protection, minimizing external parts count and reducing system cost. The FAN7311 typically consumes less than 4mA of operating current, improving overall system efficiency. It supports analog and burst dimming modes and provides open lamp regulation and protection.

ATS278 is a single chip Hall effect latch with frequency generator (FG) output, which is designed for electronic commutation of two-phase brush-less DC fan applications.

This application note describes how to build variable output voltage Boost PFC converters using the FAN9612 Interleaved BCM PFC controller. By adjusting the output voltage, flexible control can be achieved based on the input AC rms voltage level or the output power of the converter. The document also explains different levels of circuit design and implementation.

This document is the user guide for the FAN9612 400W 4-layer evaluation board, which provides an overview of the evaluation board, key features, specifications, test procedures, schematic, etc.

ATS276/277 are integrated Hall sensors with output drivers, mainly designed for electronic commutation of brush-less DC Fan. This IC internally includes the regulator, protecting diode, Hall plate, amplifier, comparator, and a pair of open-collector outputs (DO, DOB). While the magnetic flux density (B) is larger than operate point (Bop), DO will turn on (low), and meanwhile DOB will turn off (high). Each output is latched until B is lower than release point (Brp), and then DO、DOB transfer each state. For DC fan application, sometimes need to test power reverse connection condition. Internal diode only protects chip-side but not for coil-side. If necessary, add one external diode to block the reverse power.

This document introduces the basic knowledge of MOSFET, including the history, structure, characteristics and characteristics of MOSFET

This document presents an empirical self-heating SPICE MOSFET model for vertical DMOS power MOSFETs, which accurately represents the electrical and thermal responses. This model integrates the thermal and electrical models of a VDMOS MOSFET and is independent of SPICE's global temperature definition. Existing models can be easily upgraded to self-heating models.

This paper presents a new PSPICE subcircuit that can simulate power MOSFETs over a wide range of temperatures. The subcircuit uses an empirical method to model MOSFET characteristics such as on-state and off-state resistance, gate equivalent series resistance, body diode effects, breakdown voltage, and capacitance for temperatures between -55oC and 175oC.
