15W 5V SMPS Evaluation Board with CoolSET? ICE3A1065ELJ?
Universal input power supply designed in a 5V 15W off line SMPS flyback converter topology that utilizes the ICE3A1065ELJ CoolSET?. The application board is designed for discontinuous conduction mode (DCM) with current mode controller IC and running at 100 kHz switching frequency. It has one output voltage with secondary control regulation.? The
ICE3A1065ELJ is an enhanced version of the CoolSET? especially in robustness to the system noise such as ESD, lightning surge, etc. Besides having the basic features of the F3 CoolSET? such as Active Burst Mode, propagation delay compensation, soft gate drive, latch off protection for serious fault (Vcc OVP, OTP and short winding) and auto-restart protection for general fault (OLP and Open loop), etc., it also has the BiCMOS technology design, built-in soft start time, built-in and extendable blanking time, frequency jitter feature with built-in jitter period and external latch enable pin, etc. The particular good features are the extremely low standby input power, the low EMI performance and the robustness to the system noise.
