On Semiconductor Announces 2 New USB-C PD 3.0 Devices
for Power Adapters and Battery Chargers


As high-capacity batteries are increasingly integrated into various devices, adoption of USB-C PD (Power Delivery) is growing. On Semiconductor announced on the 27th two new components compliant with the USB-C PD 3.0 standard.

The adaptive charging controller 'FAN6390' integrates the USB-C PD 3.0 programmable power supply (PPS) standard into systems, while the multi-mode flyback controller 'NCP12601' integrates offline power supplies such as adapters into systems.

The 2 new components simplify USB-C PD 3.0-based power supply design and support high power density application design.

The FAN6390 architecture supports state machine-based operation for all functions required in PD 3.0 and PPS implementation that simplifies design and manufacturing of end products. It provides high efficiency through synchronous rectifier FET drive technology and offers designers flexibility and programming capability through trim options.

On Semiconductor meets PPS constant current/constant voltage (CC/CV) requirements through a high-resolution 10-bit DAC fully compliant with the USB-C PD 3.0 standard. Additionally, it provides designers with thoroughly validated reference designs to support easier integration.

The NCP12601 variable frequency controller combines multi-mode continuous conduction mode (CCM) or discontinuous conduction mode (DCM) operation with valley switching to suit various load conditions. This approach provides higher efficiency compared to conventional fixed frequency PWM controllers.

Valley lockout and proprietary quiet skip features are added to provide low noise and improved EMI signature with reduced frequency jitter.

The NCP12601 features built-in auto-calibration and dual-level overcurrent protection (OCP) to provide OCP functionality essential for meeting standard requirements. Through low-loss VCC bias, it ensures a wide output voltage range without additional external circuits or complex transformer design.

The adjustable overpowe protection (OPP) function provides slope compensation through a single external resistor to ensure a constant output power level regardless of operating input voltage.

Additionally, it features auto-recovery or latch-type short circuit protection capability, and over-temperature protection (OTP) that can be pre-configured and uses a dedicated pin or can be combined with a multi-purpose CS pin.
