Product introduction

The TP8305B is a step-up DC/DC converter designed to drive white LEDs with a wide input voltage range (0.8~5.5V), adjustable constant current and limited current modes. The frequency conversion mode is adopted to limit the current cycle by cycle, so that the input and output currents change uniformly with the decrease of the power supply voltage. The device can drive a single high-power white LED with a single or double dry battery, and can also drive two, three or more WLEDs with a single lithium battery. The method of driving the WLEDs in series can provide equal WLED currents, resulting in uniform brightness.

The low feedback voltage of 46mV minimizes power dissipation in the current regulation resistor, improving efficiency. The current limit feedback voltage of 46mV can be set according to different needs.

The difference between TP8305B and TP8305 is that in current limiting mode, as the input voltage decreases, TP8305 input and output current

There will be a sudden change at a certain point, TP8305B adopts the frequency conversion mode to avoid this phenomenon. All other functions remain unchanged. Please refer to the last description of the specification for details.

Features

External MOS tube, adjustable output voltage, can drive high-voltage, high-power loads, such as 10V1A.

·Drive 0.3W-7W single white LED

·Can drive multiple WLED lights

·Efficiency up to 90%_·0.8V extremely low operating voltage (V DD to Vout)

·Constant current accuracy: ±5%_·Current limiting accuracy ±6%; ultra-low current limiting voltage 46mV

·Chip VDD overvoltage shutdown

·Temperature protection function (130℃ protection point)

Scope of application

Constant current source, such as LED flashlight, backlight module, etc.

Constant voltage source, such as bluetooth speaker, mobile power supply, etc.

Occasions that need to accurately limit the input current, such as LED flashlights with current limiting schemes

typical application:

Constant voltage and current limiting function to drive the load scheme.

Huawei officially released its first smart screen product, Huawei Smart Screen, in Munich, Germany. The 65-inch and 75-inch versions will be launched first, followed by 55-inch and 85-inch versions. Pre-sale will start at 0:00 on September 20.

Huawei's smart screen is equipped with the Hongmeng operating system, and the main focus is the interaction between AI smart eyes and mobile phones. Huawei defines it as the smart interaction center of the home. Huawei Smart Screen is the second smart large-screen product launched by Huawei after the Honor Smart Screen.

Starter 65 and 75 inches

The design concept of Huawei's smart screen is to magnify the functions of the mobile phone on the screen, so that the "screen" can return to the core of the family. The first product of Huawei Smart Screen selected 65- and 75-inch large screens, and used the purest color quantum dot light source as the backlight source, realizing full color gamut display, and the color gamut coverage rate was as high as 100%_NTSC.

The Huawei Smart Screen adopts a two-stage design. The thinnest part of the fuselage is 6.9 mm, and the thickness of the fuselage is comparable to that of the Huawei P30 Pro mobile phone. This can be regarded as a "thin" model for an LCD screen.

Huawei Smart Screen has also added the necessary interfaces for traditional large-screen products, such as HDMI, USB 3.0, video input, network input, SPDIF, wireless input interface, etc.

In terms of appearance, the most conspicuous sound bar is Huawei's Sound bar. In addition, according to Huawei's official introduction, this Sound Bar is made of 13,440 sound holes made of aluminum alloy, which is not only beautiful, but also perfectly adapts to the sound effect. In the middle of the speaker, Huawei Smart Screen has added a Xiaoyixuan screen, which will change colors according to different working states when it is turned on and playing music.

There is also a lift-type AI camera on the top of the Huawei smart screen, which supports taking pictures and video calls, etc., and it can also bring more AI capabilities to the Huawei smart screen.

AI camera multi-play

Before the release of Huawei's smart screen, Huawei has repeatedly emphasized that this is a smart screen product, not a TV, but the future of TV. Not only does he have the functions on the mobile phone, but the screen projection interaction with Huawei mobile phones is also very interesting.

Main products: ESD electrostatic diodes, TVS diodes, battery charging and management power supplies, MOS tubes, LDO low-power voltage regulators.
