说明
The TPS65130/1 is dual-output dc-dc converter generating a positive output voltage up to 15 V and a negative output voltage down to –15 V with output currents in a 200 mA range in typical applications, depending on input voltage to output voltage ratio. With a total efficiency up to 85% the device is ideal for portable battery powered equipment. The input voltage range of 2.7 V to 5.5 V allows the TPS65130/1 to be directly powered from a Li-Ion battery, from 3 cells NiMH/NiCd or alkaline batteries. The TPS65130/1 comes in a small 4 mm x 4 mm QFN-24 package. Together with a minimum switching frequency of 1.25 MHz it enables designing small power supply applications since it requires only a few small external components.
The converter operates with a fixed frequency PWM control topology and, if Power Save Mode is enabled, it uses a pulse-skipping mode at light load currents. It operates with only 500 µA device quiescent current. Independent enable pins allow power up and power down sequencing for both outputs. The device has an internal current limit overvoltage protection and a thermal shutdown for highest reliability under fault conditions.

供应线性稳压器IC TPS74201RGWr 和 TPS74201KTWr
信息内容：德州仪器的单输出 LDO 线性稳压器IC TPS74201RGWr 和 TPS74201KTWr单路输出 LDO、1.5A、可调节电压（0.8 至 3.3V）、任意电容或无电容、可编程软启动TI 主页 > 半导体 > 电源管理 > 线性稳压器 > 单通道 LDO > tps74201 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...
供应10位8通道串行DAC芯片TLV5631IDWr和TLV5631IpWr

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...
