The FAN5250 is a single output power controller to power mobile CPU cores. The FAN5250 includes a 5-bit digital-to-analog converter (DAC) that adjusts the core PWM output voltage from 0.6VDC to 1.75VDC, and may be changed during operation. Special measures are taken to allow the output to transition with controlled slew rate to comply with Transmeta's LongRun™ and Intel's P3-M Speed-Step™ requirements.

The FPF2123, FPF2124, and FPF2125 are a series of load switches which provide full protection to systems and loads which may encounter large current conditions. These devices contain a 0.125Ω current-limited P-channel MOSFET which can operate over an input voltage range of 1.8-5.5V. The current limit is settable using an external resistor. Internally, current is prevented from flowing when the MOSFET is off and the output voltage is higher than the input voltage. Switch control is by a logic input (ON) capable of interfacing directly with low voltage control signals. Each part contains thermal shutdown protection which shuts off the switch to prevent damage to the part when a continuous over-current condition causes excessive heating.

This document introduces the Fairchild Power Switch(FPS) product family, which is specially designed for off-line SMPS with minimal external components. The product includes high voltage power SenseFET and current mode PWM IC. Compared to discrete MOSFET and controller or RCC switching converter solution, the included PWM controller features integrated fixed oscillator, under voltage lock out, leading edge blanking, optimized gate turn-on/ turn-off driver, thermal shut down protection, over voltage protection, and temperature compensated precision current sources for loop compensation and fault protection circuitry. The product can reduce total component count, design size, weight and at the same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for cost-effective design in either a flyback converter or a forward converter.

The FST34X2245 is a 32-bit high speed CMOS TTL-compatible bus switch with 25Ω series resistors in outputs from Fairchild.

This document describes the features and characteristics of the KA78XX/KA78XXA series of three-terminal positive regulators produced by Fairchild Semiconductor Corporation. These regulators have an output current of up to 1A, multiple selectable output voltages, thermal overload protection, short circuit protection, etc. They employ internal current limiting, thermal shutdown, and safe operating area protection, making them virtually indestructible. With adequate heat sinking, they can deliver over 1A of output current. Although primarily designed as fixed voltage regulators, they can be used with external components to obtain adjustable voltages and currents.

Its maximum rated collector-base reverse voltage is -50V, collector-emitter voltage is -50V, emitter-base voltage is -10V, and maximum collector current is -100mA. Its maximum collector power dissipation is 300mW and its working temperature range is -55℃~150℃.

The FAN7527B is a simple and high-performance active power factor correction controller, optimized for electronic ballasts and low power, high-density power supplies.

The FAN7554 is a fixed frequency current mode PWM controller, specially designed for off-line and DC to DC converter applications with minimal external components

The ML4818 is a complete phase modulation control IC suitable for full bridge soft switching converters. Unlike conventional PWM circuits, the phase modulation technique allows for zero-voltage switching transitions and square wave drive across the transformer. The IC modulates the phases of the two sides of the bridge to control output power. The ML4818 can be operated in current mode. The delay times for the outputs are externally programmable to allow the zero-voltage switching transitions to take place. Pulse-by-pulse current limit, integrating fault detection, and soft start reset are provided. The under-voltage lockout circuit features a 6V hysteresis with a low starting current to allow off-line start up with a low power bleed resistor. A shutdown function powers down the IC, putting it into a low quiescent state.

The FAN2011/FAN2012 is a high-efficiency, low-noise synchronous PWM current mode buck regulator designed for low voltage applications. It features 95% efficiency, adjustable output voltage, 4.5V to 5.5V input voltage range, and up to 1.5A output current.

The USB1T20 is a generic USB 2.0 compliant transceiver from Fairchild Semiconductor Corporation. It supports full speed (12Mbit/s) and low speed (1.5Mbit/s) data transmission. The transceiver can be used in industry standard TSSOP and Fairchild's ultra-small 2.5mm x 2.5mm MLP packages, making it ideal for ultra-portable electronic products and other space constrained applications.
