Multi-mode, Forced-frequency-resonant Digital Controller IC

News

Infineon Technologies AG launches the XDP digital power XDPS21071, the first flyback controller in the industry with zero-voltage switching (ZVS) on the primary side to achieve high efficiency. This controller is aimed at fast-charging applications such as USB-PD or QuickCharge. Light-load efficiency is optimized for variable output application.

The XDPS21071 is a high-performance digital flyback controller with an integrated dual-MOSFET gate driver and a 600 V depletion startup unit. The primary-side controller drives a high-voltage external MOSFET in a flyback topology and an external low-voltage MOSFET to create a pulse for achieving ZVS condition at the high-voltage MOSFET. It supports fixed-frequency switching up to 140 kHz.

The patented forced-frequency-resonant (FFR) switching scheme is implemented by means of a digital algorithm, which is configurable via parameter settings (UART port is included) to meet application requirements and the conversion efficiency of international regulatory standards (i.e., EU CoC version 5 Tier 2 and DoE Level VI). Ease of design and system optimization are made possible thanks to the intelligent, self-adaptive multi-mode operation that matches each line/load conditions with the best-fit operational mode (i.e., FFR, CrCM, burst mode) for unparalleled system performance. Hereby ZVS operation enables for lowest switching losses. Highest system performance is achieved by only a minimal adder in BOM cost. This controller comes with adaptive overcurrent protection. It is lead-free and RoHS compliant.
