LD6612USB Power Delivery Controller
The LD6612 is an USB Power Delivery (USB PD) Type-C controller in the secondary side for highly efficient and slim form factor off-line AC-DC design. An 8-bit MCU is embedded to handle PD protocol, policy engine and device policy manager with built-in Bi-phase Mark Coding (BMC) for USB PD communication or other proprietary protocols (e.g.QC2.0/QC3.0).
To minimize external components, it integrates shunt regulator, voltage and current monitor and control circuit of blocking N-MOSFET. Build-in regulators provides 4.8V for MCU and peripherals to operate at single power supply from 3.3 to 24V.
