IP5318 Inch Core Fast Charge Mobile Power Solution Introduction
Qualcomm introduced QC3.0 fast charging technology, and is committed to the highly integrated mobile power solutions leader, Integral Technology, and released the world's first all-in-one fast charging mobile power single-chip solution IP5318. The chip uses a number of industry-first technologies that, when used with adaptive voltage protocols such as QualcommQuickCharge 3.0 or type-c, enable smart mobile device manufacturers to reduce the charging time of many products. Developers use adaptive charging technology to significantly reduce charging time and increase charging efficiency, while also being compatible with previous 5V output universal chargers using the USBBC 1.2 specification, which minimizes thermal management and battery charging systems. The cost of the cost.

The charging IP5318 has a constant current, constant voltage lithium battery charging management system that supports high-voltage charging synchronous switch structure. Optimized for 5V, 9V, 12V charging voltage, it can automatically match different charging voltage specifications.
When the battery voltage is less than 3V, 400mA trickle charging is used; when the battery voltage is greater than 3V, it enters constant current charging, the constant current maximum charging current is 4.8A; when the battery voltage is close to the set battery voltage, it enters constant voltage charging. After the charging is completed, if the battery voltage is lower than the set battery voltage by 0.1V, turn the battery charging back on.
IP5318 uses switching charging technology, switching frequency of 500kHz, maximum charging current of 4.8A, charging efficiency up to 97%, can shorten the charging time of 3/4.
The IP5318charger automatically adjusts the charging current to accommodate adapters with different load capacities, ensuring that the adapter is not pulled.
The IP5318 does not support the same charge and discharge. The output discharge port is turned off during the charging process to prevent the input high voltage from damaging the charged device.
BoostThe IP5318 integrates a synchronous switching converter system that supports high-voltage output, and supports different voltages such as 5V, 9V, and 12V. The load capacities are 5V-3.1A, 9V-2.0A, and 12V-1.5A.
The switching frequency is 375KHz. The built-in soft start function prevents the inrush current caused by excessive startup, causing faults, integrated output overcurrent, short circuit, overvoltage, over temperature and other protection functions to ensure stable and reliable operation of the system.
The boost system output current is automatically adjusted with temperature to ensure that the IC temperature is below the set temperature.

A new rule from the Drug Enforcement Administration (DEA) threatens to upend the American hemp industry, and could even result in criminal prosecutions for manufacturers of CBD and delta-8 THC products.
The DEA says the [interim final rule," issued Aug. 20, is simply a matter of adjusting its own regulations to account for changes to the Controlled Substances Act that were mandated by the 2018 Farm Bill (or Agricultural Improvement Act) that legalized hemp and CBD production. The new rule [merely conforms DEA`s regulations to the statutory amendments to the CSA that have already taken effect," says the agency. The new rule doesn`t break any ground, according to the DEA.
But many experts on cannabis and hemp law say the DEA rule creates a potential pathway the law enforcement agency could use to prosecute hemp processors and producers of CBD (cannabidiol) and delta-8 THC (or Δ8THC) products. There are two issues: partially processed CBD, and [synthetically derived" delta-8 THC.
