The LT3825 is an isolated switching regulator controller designed for medium power flyback topologies. It features sensing output voltage directly from the primary side winding without an optoisolator, improving dynamic response and reliability. It also has synchronous rectification to increase converter efficiency and improve output cross regulation in multiple output converters. The LT3825 operates in forced continuous conduction mode, improving cross regulation.

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.

The LT3012B is a high voltage, micropower low dropout linear regulator. The device is capable of supplying 250mA of output current with a dropout voltage of 400mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (40µA operating) makes the LT3012B an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3012B include the ability to operate with very small output capacitors. The regulators are stable with only 3.3µF on the output while most older devices require between 10µF and 100µF for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available with an adjustable output with a 1.24V reference voltage.

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 CS5531/32/33/34 are highly integrated ∆Σ Analog-to-Digital Converters (ADCs) which use charge-balance techniques to achieve 16-bit (CS5531/33) and 24-bit (CS5532/34) performance. The ADCs are optimized for measuring low-level unipolar or bipolar signals in weigh scale, process control, scientific, and medical applications.

The ADC122S021 is a low-power, two-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface. It is unlike the conventional practice of specifying performance at a single sample rate only, the ADC122S021 is fully specified over a sample rate range of 50 kSPS to 200 kSPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept one or two input signals at inputs IN1 and IN2. The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROW- IRE, and many common DSP serial interfaces. The ADC122S021 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 2.2 mW and 7.9 mW, respectively. The power-down feature reduces the power consumption to just 0.14 µW using a +3V supply, or 0.32 µW using a +5V supply. The ADC122S021 is packaged in an 8-lead MSOP package. Operation over the industrial temperature range of −40˚C to +85˚C is guaranteed.

The LP3878-ADJ is a 800mA adjustable output voltage regulator designed by TI. It features low quiescent current, low noise and low temperature drift. It is suitable for applications that require output voltage as low as 1.0V.

The LTC 3440 is a high efficiency, fixed frequency, Buck- Boost DC/DC converter that operates from input voltages above, below or equal to the output voltage

AD9215 is a 10-bit, 65/80/105 MSPS, 3V A/D converter with features such as single 3V supply operation, high signal-to-noise ratio, low power consumption, and flexible analog input.

LM5100A/LM5101A 3.0 Amp High Voltage High Side and Low Side Driver. This product is produced by Texas Instruments and is suitable for a variety of power conversion applications, such as current fed push-pull converters, half-bridge and full-bridge power converters.

The MAX1110/MAX1111 are low-power, 8-bit, 8-channel analog-to-digital converters (ADCs) that feature an internal track/hold, voltage reference, clock, and serial interface. They operate from a single +2.7V to +5.5V supply and consume only 85µA while sampling at rates up to 50ksps. The MAX1110’s 8 analog inputs and the MAX1111’s 4 analog inputs are software-configurable, allowing unipolar/bipolar and single-ended/differential operation. Successive-approximation conversions are performed using either the internal clock or an external serial-interface clock. The full-scale analog input range is determined by the 2.048V internal reference, or by an externally applied reference ranging from 1V to VDD. The 4-wire serial interface is compatible with the SPI™, QSPI™, and MICROWIRE™ serial-interface standards. A serial-strobe output provides the end-of-conversion signal for interrupt-driven processors. The MAX1110/MAX1111 have a software-programmable, 2µA automatic power-down mode to minimize power consumption. Using power-down, the supply current is reduced to 6µA at 1ksps, and only 52µA at 10ksps. Power-down can also be controlled using the SHDN input pin. Accessing the serial interface automatically powers up the device. The MAX1110 is available in 20-pin SSOP and DIP packages. The MAX1111 is available in small 16-pin QSOP and DIP packages.
