说明
The TPS742xx low-dropout (LDO) linear regulators provide an easy-to-use robust power management solution for a wide variety of applications. User-programmable soft-start minimizes stress on the input power source by reducing capacitive inrush current on start-up. The soft-start is monotonic and well suited for powering many different types of processors and ASICs. The enable input and power-good output allow easy sequencing with external regulators. This complete flexibility permits the user to configure a solution that will meet the sequencing requirements of FPGAs, DSPs, and other applications with special start-up requirements.
A precision reference and error amplifier deliver 1% accuracy over load, line, temperature, and process. Each LDO is stable with low-cost ceramic output capacitors and the family is fully specified from –40°C to +125°C. The TPS742xx is offered in a small (5mm × 5mm) QFN package, yielding a highly compact total solution size. For applications that require additional power dissipation, the DDPAK (KTW) package is also available.

供应10位8通道串行DAC芯片TLV5631IDWr和TLV5631IpWr
信息内容：德州仪器的10 位 8 通道串行 DAC 芯片TLV5631IDWr和TLV5631IpWrTI 主页 > 半导体 > 数据转换器 > 数模转换器 > 精密 DAC (=<10MSPS) > TLV5631IDWr具有内部参考的 2.7V 至 5.5V 10 位 8 通道串行 DAC 8-Channel, 12-/10-/8-Bit, 2.7-V to 5.5-V, Low Power DAC with Power Down 说明The TLV5630, TLV5631, and TLV5632 are pin-compatible,eight-channel, 12-/10-/8-bit voltage output DACs each with a flexible serial interface. The serial interface allows glueless interface to TMS320 and SPI, QSPI, and Microwire serial ports. It is programmed with a 16-bit serial string containing 4 control and 12 data bits. Additional features are a power-down mode, an LDAC input for simultaneous update of all eight DAC outputs, and a data output which can be used to cascade multiple devices, and an internal programmable band-gap reference. The resistor string output voltage is buffered by a rail-to-rail output amplifier with a programmable settling time to allow the designer to optimize speed vs power di...
供应TI 的高效升压降压转换器IC TPS63000DRCR
信息内容：TI 的具有 1.8A 电流开关的 96% 升压降压转换器IC TPS63000DRCR 半导体 > 电源管理 > 开关稳压器 > DC/DC 转换器（集成开关） > 升压 - 降压稳压器 > TPS63000 High Efficient Single Inductor Buck-Boost Converter with 1.8-A Switch 说明 The TPS6300x devices provide a power supply solution forproducts powered by either a two-cell or three-cell alkaline, NiCd or NiMH battery, or a one-cell Li-Ion or Li-polymer battery. Output currents can go as high as 1200 mA while using a single-cell Li-Ion or Li-Polymer Battery, and discharge it down to 2.5V or lower. The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters Power Save mode to maintain high efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to operate at a fixed switching frequency. The maximum average current in the switches is ...
