Description
The RT7740 series is an enhanced high-efficiency multimode PWM flyback controller, incorporating Richtek’s proprietary SmartJitterTM technology.
Features
- a multi-mode control scheme, operating from continuous-conduction mode (CCM) to discontinuous-conduction mode (DCM) with valley switching, to achieve high efficiency and optimal performance. The RT7740 is a current-mode PWM controller for flyback converters. It integrates comprehensive and programmable protection features, which include propagation delay compensation, output over-voltage protection (OVP), external over-temperature protection (OTP), and bulkcapacitor brown-in/brown-out protection.
