RDK-848 is a 42 W dual USB port switching power supply for wall outlet and power strip pad application. The main power supply is an isolated flyback controlled by INN3379C InnoSwitcw3-Pro. It is designed to deliver 30 W USB PD 3.0 (USB Type-C) and at the same time, provide DC input supply for 5 V / 2.4 A output (USB Type-A) DC/DC converter.
InnoSwitch3-Pro is a highly integrated digitally controllable quasi-resonant flyback switcher IC designed for high efficiency USB PD 3.0 application. It integrates a highvoltage switch, primary and secondary side control and fluxLink feedback which simplifies the development of fully programmable, highly efficient power supplies, particularly those in compact enclosures. InnoSwitch3-Pro has built-in 3.3 V linear regulator that provides a bias supply for the microprocessor in stand-alone implementations. The IC uses the universal I2C interface that enables dynamic control of output voltage and current along with many configurable features.
RDK-848 offers low component count and heat sink-less design for compact enclosure applications. The key design goals were high efficiency and compact design.
