Description

GG105X is a high-performance dual-winding chip for PSR chargers, designed mainly for lithium battery chargers. It eliminates the auxiliary winding of the transformer, integrates current sampling resistors, and optimizes system costs. GG105X achieves high-precision constant voltage function through a built-in programmable module, and can directly charge lithium batteries; built-in LED light function, the precise light current point can accurately indicate the charging status. The chip realizes constant current and constant voltage functions by detecting the current and voltage of the primary side of the transformer, and has built-in loop stability compensation, which can omit TL431, optocoupler and auxiliary winding power supply.
