SLM6335

SLM6335 is a 2.5A lithium ion battery charger for 5V adapter. It is a synchronous buck converter with a fixed frequency of 550kHz. It has a charging efficiency of more than 90% and a very small calorific value. SLM6335 integrates 28V high- voltage devices, which can effectively prevent chip is damaged by surge voltage or incorrect connection of high- voltage adapter, and has high security. The SLM6335 includes a complete charging termination circuit, automatic recharging and a 4.35V preset charging voltage with an accuracy of ±1%. The SLM6335 has many functions, such as anti back filling protection, output short circuit protection, chip and battery temperature protection. SLM6335 is packaged in a miniaturized DFN3x3- 10L package, which requires only a small number of peripheral components and a very small area of PCB board. Therefore, SLM6335 can be embedded in various handheld applications as an efficient charger for large capacity batteries.
