Introduction

AI Translation

The UCC24630 SR controller is a high-performance controller and driver designed for N-channel MOSFET power devices used in secondary-side synchronous rectification. The combination of the controller and the MOSFET forms an almost ideal diode rectifier. This solution not only directly reduces the power consumption of the rectifier but also reduces the primary-side losses through improved efficiency. The UCC24630 uses the volt-second balance control method and is not directly connected to the drain of the MOSFET, making it an ideal choice for flyback power supplies over a wide output voltage range. The SR drive turn-off threshold is independent of the MOSFET RDS(on), which optimizes the maximum on-time. Additionally, the secondary-side current ringing caused by the device and wiring inductance does not affect the SR turn-off threshold. The UCC24630 controller provides a programmable error trigger filter, a frequency detector (which can automatically switch to standby mode during low-power states), and pin fault protection. The UCC24630 is compatible with three operating modes: discontinuous conduction mode (DCM), transition mode (TM), and continuous conduction mode (CCM). With its wide VDD operating range and a wide range of programmable VPC voltages and blanking times, this device can be used in various flyback converter designs.
