bq24630 is a highly integrated switch-mode battery charge controller designed specifically for Lithium Phosphate battery

tps54418 is a high efficient 4a synchronous step down chip launched by ti. it integrates two 30 mΩ mosfets, supports 200khz to 2mhz switching frequency, and uses qfn package, which is small and can be used in various switch power supply designs.

The TPS6300x series is a high-efficiency single-inductor buck-boost converter with 1.8-A switches, an input voltage range of 1.8V to 5.5V, and a fixed output voltage of 3.3V. The output current can be as high as 1200 mA. This series of products is suitable for products powered by two or three alkaline, nickel-cadmium or nickel-metal hydride batteries or a single lithium-ion or lithium-polymer battery.

The THS412x is a high-performance fully differential I/O amplifier with 100 MHz, -3 dB bandwidth, 50 V/µs slew rate, 75 dB total harmonic distortion (VO = 2 VPP) and 5.4 nV/√Hz input-referred noise (10 kHz). The amplifier is fabricated using Texas Instruments' state-of-the-art submicron CMOS process and is a 1-channel differential input/differential output device.

The OPA227 and OPA228 series op amps combine low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both ac and preci- sion dc performance. The OPA227 is unity-gain stable and features high slew rate (2.3V/µs) and wide bandwidth (8MHz). The OPA228 is opti- mized for closed-loop gains of 5 or greater, and offers higher speed with a slew rate of 10V/µs and a bandwidth of 33MHz. The OPA227 and OPA228 series op amps are ideal for professional audio equipment. In addition, low quiescent current and low cost make them ideal for portable applica- tions requiring high precision. The OPA227 and OPA228 series op amps are pin-for-pin replacements for the industry standard OP-27 and OP-37 with substantial improvements across the board. The dual channel versions provide higher output current and higher output swing.

The ADS8331/ADS8332 is a low-power, 16-bit, 500k samples per second (SPS) analog-to-digital converter with a unipolar, 4:1 multiplexer (mux) input and a serial interface.

The SN65HVD08 and SN75HVD08 are RS-485 transceivers from TI with wide supply voltage range, low quiescent current and 1/8th unit load

The TPS4030x is a family of cost-optimized synchronous buck controllers that operate from 3-V to 20-V input. The controller implements a voltage-mode control architecture with input-voltage feed-forward compensation that responds instantly to input voltage change. The switching frequency is fixed at 300 KHz, 600 KHz or 1.2 MHz. Frequency Spread Spectrum feature adds dither to the switching frequency, significantly reducing the peak EMI noise and making it much easier to comply with EMI standards. The TPS4030x has good EMI performance and can be used in various applications such as POL modules, printers, digital TVs and telecommunications.

High Precision, Low Noise OPERATIONAL AMPLIFIERS

The AM26LV32 is a BiCMOS, quadruple, differential line receiver with 3-state outputs, designed to be similar to TIA/EIA-422-B and ITU Recommendation V.11 receivers, but with a reduced common-mode voltage range due to reduced supply voltage. The device is optimized for balanced bus transmission at switching rates up to 32 MHz. The enable function is common to all four receivers and offers a choice of active-high or active-low inputs. The 3-state outputs permit direct connection to a bus-organized system. Each device features receiver high input impedance and input hysteresis for increased noise immunity, and input sensitivity of ±200 mV over a common-mode input voltage range from −0.3 V to 5.5 V. When the inputs are open circuited, the outputs are in the high logic state. This device is designed using the Texas Instruments (TI) proprietary LinIMPACT-C60 technology, facilitating ultra-low power dissipation.

CC2500 is a low cost true single chip 2.4 GHz transceiver designed for very low power wireless applications. Applications include 2400-2483.5 MHz ISM/SRD band systems, consumer electronics, wireless game controllers, wireless audio and wireless keyboard and mouse.

The TPS40192/3 are cost-optimized synchronous buck controllers that operate from 4.5 V to 18 V input. These controllers implement a voltage-mode control architecture with the switching frequency fixed at either 600 kHz (TPS40192) or 300 kHz (TPS40193). The higher switching frequency facilitates the use of smaller inductor and output capacitors, thereby providing a compact power-supply solution. An adaptive anti-cross conduction scheme is used to prevent shoot through.

The TPS6102x series is a high efficiency synchronous boost converter with an adjustable output voltage, an input voltage range of 0.9V to 6.5V, and an output current of up to 200mA. It can be used for products powered by a single-cell, two-cell, or three-cell alkaline, nickel cadmium, or nickel metal hydride battery, or it can be used to generate 5V at 500mA from a 3.3V or Li-Ion battery.
