The onsemi NCP13992ACDR2G is a high-performance current-mode resonant controller designed for half-bridge LLC resonant converters. It integrates 600 V gate drivers directly on-chip, simplifying PCB layout and reducing external component count. The controller implements a current-mode control scheme with automatic dead-time adjustment, enabling efficient zero-voltage switching (ZVS) across varying load conditions. A proprietary quiet skip mode minimizes transformer acoustic noise during light-load operation. The device includes a dedicated output to control an external PFC stage, optimizing overall system efficiency. Comprehensive protection features include overload, over-current, brown-out, open optocoupler detection, OVP, OTP, and out-of-resonance protection. The NCP13992 also features Dynamic Self-Supply (DSS) operation and an extremely low-leakage startup current source.

The NCP13992ACDR2G controls a half-bridge LLC resonant converter using current-mode regulation. The controller adjusts the switching frequency to regulate the output voltage — higher frequency reduces output voltage, lower frequency increases it. An internal current-sense circuit monitors the primary resonant current, and the on-time is modulated based on both the feedback signal and the sensed current. Automatic dead-time adjustment optimizes ZVS by detecting the half-bridge mid-point voltage transitions (dV/dt sensing) and setting the optimal dead-time between high-side and low-side switch transitions. During light-load conditions, the controller enters quiet skip mode, where switching bursts are regulated by an internal digital controller to minimize acoustic noise. The integrated 600 V level-shifter and bootstrap circuitry drive the high-side MOSFET without requiring an external driver IC. A PFC control output signal manages the front-end PFC stage, disabling it during light-load to reduce standby power.
