Common questions
Dioo manufactures LDO regulators, buck and boost converters, battery charger ICs, load switches, overvoltage and overcurrent protection devices, current sensors, and LED drivers. Its signal-chain portfolio includes operational amplifiers, audio power amplifiers, analog switches, USB switches, MIPI switches, LCD bias drivers, flash drivers, and audio and video signal-conditioning components.
The DIO8650E combines single-stage flyback conversion with power-factor correction for LED lighting applications. It operates as a primary-side controller, eliminating the need for a secondary feedback circuit and reducing external component requirements.
Dioo’s DIO8650E is one of its most well-regarded products. This single-stage fly-back and PFC controller is designed for LED lighting applications. A primary-side controller drives the device in quasi-resonant mode to achieve higher efficiency. The item simultaneously avoids the use of a secondary feedback circuit. The DIO8650E maintains a constant on-time operation to provide a high power factor. This chip has a unique design that allows for a quick start-up and offers reliable protection. The DIO7708 is an LDO linear voltage regulator with a current rating of 300mA. It is a very stable and precise device with extremely low quiescent current consumption, typically 4A over the entire temperature range. It also has a wide input voltage range, up to 30V, and thermal shutdown to provide superior protection. The DIO5538B/C/D is a full-featured constant current/voltage linear charger for single-cell Lithium-Ion batteries. Because of the internal MOSFET architecture, it requires an external sense resistor. It features thermal feedback controls to keep the die temperature low during high-power operations or amid high ambient temperatures. Plus, it possesses fixed charge voltage, and its charge current is externally programmable with a single resistor. Also, when the charge current falls to 1/10 of the programmed value after it reaches the final float voltage, the DIO5538B/C/D automatically terminates the charging cycle.
