MHW-N1922 Smart USB Fast Charging Products

[#1]

The problem of smartphones running out of battery power too soon during the day is well known and in response new fast charging standards have been introduced, ranging from multi-level output ones like USB Power Delivery and Quick Charge to 5V/multi-Amp proprietary Direct Charging protocols. This drives the demand for AC/DC converters with high efficiency over an adjustable 3-20V range, small size, good load step response and very low no-load power. NXP introduces a complete AC/DC fast charging system covering all these requirements, comprising the TEA1936 fly-back controller, the TEA1993/98 synchronous rectifier and the TEA190x family of protocol controllers that communicate with the device to be charged. The TEA190x family supports all mainstream fast charging protocols, is highly configurable and enhances charger safety by an extensive set of hardware integrated protection features.
