描述 Description

HY923 is a smart digital control synchronous rectifier controller functioning as diode emulator. It drives the standard N-channel Power MOSFET to replace Schottky in order to achieve the high efficiency. HY923 incorporates the digital control technology to optimize the multi-mode operation at DCM / PFM / CCM / QR in the different applications. The digital control technology further enhances the robust CCM operation. Adaptive pre-turning off scheme not only guarantees the fast transition but also minimizes switching loss. The adaptive pre-turn off scheme optimizes the EMI due to the soft SR MOSFET switching off transition. The configurable volt- second threshold through INTG pin avoids SR MOSFET mis-trigger transition due to the parasitic ring under DCM/QR mode. HY923 integrates the multi features to minimize the BOM and optimize the performance.(1)HY923 is available with SOT23-6 package.(1)
