NU2135 is a 98.0% efficient, 9-A battery charging solution using a switched cap architecture. This architecture and the integrated FETs are optimized to enable a 50% duty cycle, allowing the cable current to be half the current delivered to the battery, reducing the losses over the charging cable as well as limiting the temperature rise in the application. The dualphasearchitecture reduces the input cap requirements as well as reducing the output voltage ripple.

NU17123 are a high efficiency, high integration Qi2 compliant transmitter IC for wireless charging.
NU17123 integrate low Rdson Full bridge FETs and gate driver, 32bit 36MHz MCU core, 8KB SRAM and 128KB Flash, and fast charging block TCPC/PD/BC1.2/QC3.0/UFCS/FCP/SCP/AFC.
NU17123 integrate all critical functions of power system, such us low -EMI FET drivers, Bootstrap circuits for external resonant capacitor switches, 4.8V/3.3V/1.5V LDO and 5V Buck converter power supply, high -accuracy current measurement. Controllable slew rate/ dead time of gate driver and PWM frequency dither function can further reduce the EMI of power system.
