[introduction] the progress as the technology, can apparel the function with the sort of individual electron product and compositive place is increasingly rich, for example glasses of annulus of hand of intelligent watch, intelligence, AR, more and more person selected choose are bought use this kind of product. To promote an user the experience further, lengthen can apparel a when the service life of the batteries in equipment becomes developer to be faced with serious challenge. TI is new the TPS61299 of step up converter that roll out is had exceed small static electric current, can satisfy effectively can apparel long this one demand when equipment bides his time to lengthening.

The static electric current of TPS61299 is small to 95nA, advanced level is in in industry. In the meantime, the energy changeover efficiency of TPS61299 is very tall, for example, in the input the 2V, condition that outputs 3.3V/200mA falls, efficiency is as high as 94% . These character can lengthen the batteries in the system effectively bide one’s time time and service life, contented can apparel the design requirement of product of type individual electron, bring better user experience thereby.

The limits of input electric current of TPS61299 comes for 0.7V 5.5V, contented great majority can apparel the batteries voltage limits of electronic product, output voltage limits comes for 1.8V 5.5V. To satisfy the requirement of different application setting, TPS61299 series has different input electric current to restrict version, include 5mA, 25mA, 50mA, 100mA and 1.2A, value of limitation of electric current of input of correspondence of particular material date explains with Datasheet to allow.

In addition, new generation TPS61299 optimized the expression that parts of an apparatus is answering career respect, have at the same time involve character really, developer is OK according to systematic demand, choose compulsive PWM mode mode of automatic perhaps PFM. We are what converter of this step up offers two kinds of forms to enclose, it is dimension is enclosed for the SOT of 1.2mm X 1.6mm and dimension is enclosed for the WCSP of 1.2mm X 0.8mm respectively, can satisfy the diversiform requirement of broad client.

Current, most common can apparel the product is intelligent watch or intelligent hand annulus, wait for biology signal to measure the hematic oxygen of the person that adorn, heartbeat, the meeting in intelligent watch is normally useful the optical sensor module that detects at biology signal, TPS61299 of step up converter can be used at having power supply for this kind of module. Generally speaking, biology signal detects module is not work continuously, however removed period of time undertakes collection to signal, the step up converter that this is about to seek front has inferior static electricity in order to reduce energy loss, also need high-speed trends to answer the signal that will make sure implementation is accurate to collect at the same time. TPS61299 optimized these function on the foundation of TPS61099, make new generation product can satisfy client system design requirement better.

The star product in the step up converter that released 2023 as heart state apparatus, TPS61299 exceeds electric current of small static state, efficient, fast trends to answer with its, the advantage such as small size is significant the ground is comfortable the application that equipment can apparel in distributing individual electron product. You can examine a product in official product page the data such as documentation of detailed information, technology, or buy this product to reach evaluate edition.
