The XTR110 is a precision voltage-to-current converter designed for analog signal transmission. It accepts inputs of 0 to 5V or 0 to 10V and can be connected for outputs of 4 to 20mA, 0 to 20mA, 5 to 25mA and many other commonly used ranges.

The TLV277x CMOS operational amplifier family combines high slew rate and bandwidth, rail-to-rail output swing, high output drive, and excellent dc precision.

Low-voltage adjustable precision shunt regulators

The TPA302 is a stereo audio power amplifier from TI that can deliver 300mW of continuous average power into an 8-ohm load at less than 0.06% THD+N from a 5-V power supply or up to 300mW at 1% THD+N.

The TL284x and TL384x series of control integrated circuits provide the features necessary to implement off-line or dc-to-dc fixed-frequency current-mode control schemes with a minimum number of external components. Some of the internally implemented circuits are an undervoltage lockout (UVLO) with a start-up current of less than 1 mA and a precision reference trimmed for accuracy at the error amplifier input. Other internal circuits include logic for latched operation, a pulse-width modulation (PWM) comparator (that also provides current-limit control), and a totem-pole output stage designed to source or sink high-peak current. The output stage, suitable for driving N-channel MOSFETs, is low when it is in the off state. Major differences between members of these series are the UVLO thresholds and maximum duty-cycle ranges.

UCC28C4x family are high performance current mode PWM controllers featuring 2.3 mA operating current, 25 ns rise and 20 ns fall time rail-to-rail output swings, ±1 A peak output current, 35 ns cycle-by-cycle overcurrent limiting, 1 MHz operation, suitable for switch mode power supplies, DC-DC converters and board mount power modules.

The TPA2005D1 is a 1.4-W high-efficiency filter-free class-D audio power amplifier in a MicroStar Junior™ BGA, QFN, or MSOP package that requires only three external components.

The ADS7818 is a 12-bit sampling analog-to-digital converter (A/D) complete with sample/hold, internal 2.5V reference, and synchronous serial interface. It has low power, small size, and high-speed characteristics, making it ideal for battery operated systems such as wireless communication devices, portable multi-channel data loggers, and spectrum analyzers. It also provides low-cost isolation for remote data acquisition.

the tlv2470 is a low-power, high-drive cmos switching power supply amplifier that offers 2.8mhz of gain-bandwidth product, operating over a supply voltage range of 2.7v-6v. it is available in 5- or 6-pin sot-23 and 8- or 10-pin msop packages.

UCC3583 is a synchronizable secondary side post regulator for precision regulation of the auxiliary outputs of multiple output power supplies. It contains a leading edge pulse width modulator, which generates the gate drive signal for a FET power switch connected in series with the rectifying diode. The turn-on of the power switch is delayed from the leading edge of the secondary power pulse to regulate the output voltage.

TPS61020 is a 96% efficient synchronous boost converter from TI. It provides 200mA output current and can operate with an input voltage range of 0.9V to 6.5V.

The UCC2891/2/3/4 family of PWM controllers is designed to simplify implementation of the various active clamp/reset switching power topologies. The UCC289x is a peak current-mode, fixed-frequency, high-performance pulse width modulator. It includes the logic and the drive capability for the auxiliary switch with a simple method of programming the critical delays for proper active clamp operation. The UCC2891/3 includes a 110-V start-up regulator for initial start-up and to provide keep-alive power during stand-by. Additional features include an internal programmable slope compensation circuit, precise DMAX limit, and a single resistor programmable synchronizable oscillator.

The UCC3807 family is a programmable maximum duty cycle PWM controller designed for off-line and dc-to-dc fixed frequency current mode switching power supplies. It features high speed, low power consumption, internal full cycle soft start, and internal leading edge blanking of the current sense input.

The DRV1100 is a fixed gain differential line driver designed for very low harmonic distortion at the high powers required of xDSL line interface standards. Operating on a single +5V supply, it can deliver 230mA peak output current and 9.5Vp-p differential output voltage swing.

The TPS74401 is a low-dropout (LDO) linear regulator that provides an easy-to-use robust power management solution for a wide variety of applications.
