Solution Description
This high-power-density USB-PD adapter includes Programmable Power Supply (PPS) mode and supports a wide range of input voltages and can deliver five fixed “Power Delivery Objects” (PDO) and two Augmented “Power Delivery Objects” (APDOs).
This solution is based on the ST-ONE, the world’s first digital controller embedding an Arm Cortex M0+ core, an off-line programmable controller with synchronous rectification, and USB PD PHY in a single package.
It includes an advanced power system-in-package (MASTERGAN4) integrating a gate driver and two enhancement mode GaN power transistors in half bridge configuration for high-switching operations which also allow the use of small magnetic components, ensuring very high efficiency.
The ST-ONE includes active clamp flyback controller and its HV startup on the primary side, a microcontroller and all the peripherals required to control the conversion and the USB-PD communication on the secondary side; With the two sides connected through an embedded galvanically isolated dual communication channel, the ST-ONE uses a novel non-complementary control technique and specifically designed power modes to reach both high efficiency and low no-load power consumption.
