On July 19, 2013, Beijing News has announced a multi-mode power management unit (PMU) that supports quiescent current of low-to-100NA ultra-low overall system, which can minimize microcontroller And the power consumption of water meter, gaute, and other industrial applications powered by the battery. The TPS65290PMU can manage all power requirements of the system, including load conditions of 100NA to 500mA. TPS65290PMU integrates three manufacturers of three support microcontrollers (MCU) sleep modes to configure "normally open" power and a automatic function that can select power from input voltage or lift converter.

In addition, TPS65290 can also be seamlessly working with MSP430MCUs such as TI ultra low power MSP430F5328. The important features and advantages of TPS65290: extending battery life: Designers can use the latest PMU low-power normally open power supply, and develop systems running more than 10 years under a single battery, so that three of the following can be supplied to MCU sleep mode. Manufacturers Optional Options: 10mA, 100NA Quick Current (IDDQ) Sleep Mode, Support for Leakage Current Bias Controller of Preset Voltage; 10mA, 400NAIDDQ Low Pressure Factor (LDO); 30mA, 300NAIDDQ Buck Converter.

Maximum reduction of board size, number of components and costs: integrated 500mA lifting voltage converter on a single 20mm2 power management chip, 150mAlDo, 8 power distribution switches, input voltage recovery comparators, state machines, and manufacturers optional SPI / I2C Interface; can be configured for a variety of applications: a large number of EEPROM configurations and programmable output voltages can provide high flexibility of designing system output voltage supply for designers. TI Industrial Simulation Products TI is a leading manufacturer of industrial semiconductor market, which can serve a variety of different series of simulated integrated circuits (IC) for smart grid, factory automation, high voltage power, LED lighting and control. TI data converters, amplifiers, interfaces, isolation devices, clocks, and power management devices help customers achieve differentiation for their products, while TI software, design tools and reference design simplifies and accelerates design processes.

The supply situation uses 24-pin, 4 mm X5 mm VQFN package TPS65290 has now available. Designers can order TPS65290BMEVM and TPS65290LMEVM evaluation board to quickly evaluate their design, accelerate product listing process. .
