Mingjiada Electronics Supply Onsemi Power Factor Controllers

As energy efficiency standards for industrial power supplies, fast-charging equipment, server power supplies, LED drivers and display power supplies continue to rise, power factor correction (PFC) chips have become core components in AC-DC power supply solutions. Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier of the full range of Onsemi power factor controllers — also offers high-value buy-back services for idle stock of Onsemi PFC chips from manufacturers and distributors, providing a one-stop solution for component procurement and inventory optimisation.

Onsemi Power Factor Controllers
Details: Onsemi PFC controllers cover a wide range of Critical Conduction Mode (CRM), Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) power factor controllers for power factor correction.

NCP1618 – Multi-Mode (CrM-CCM) Power Factor Corrector
Overview: The NCP1618 is an innovative multi-mode power factor controller. Depending on the duration of the switching cycle, the circuit can transition naturally from Critical Conduction Mode (CrM) to Continuous Conduction Mode (CCM), and vice versa, thereby optimising line/load efficiency. Under extremely light load conditions, the circuit can enter soft SKIP mode, thereby minimising losses.

NCP1680 – Totem-Pole Critical Conduction Mode (CrM) Power Factor Correction Controller
Overview: The NCP1680 is a CrM PFC controller IC designed to drive a bridge-less totem-pole PFC topology. The bridge-less totem-pole PFC is a power factor correction configuration comprising a fast-switching bridge arm driven at a PWM switching frequency and a second bridge arm operating at AC line frequency. This topology eliminates the diode bridge typically found at the input of conventional PFC circuits, resulting in a significant improvement in the efficiency of the power stage.

NCP1681 – Totem-Pole Continuous Conduction Mode (CCM)/Multi-Mode (CrM-CCM) Power Factor Correction Controller
Details: The NCP1681 is a PFC controller IC designed to drive a bridge-less totem-pole PFC topology. The bridge-less totem-pole PFC is a power factor correction configuration comprising a fast-switching bridge arm driven at a PWM switching frequency and a second bridge arm operating at AC line frequency. This topology eliminates the diode bridge typically found at the input of conventional PFC circuits, resulting in a significant improvement in the efficiency of the power stage. This controller can be configured for Continuous Conduction Mode (CCM) or Multi-Mode (CrM-CCM) operation.
