30W 12V SMPS Evaluation Board
This is a universal input 12V 30W off-line flyback converter power supply board utilizing CoolSET™ ICE3RBR0665JZ. The application evaluation board is operated in Discontinuous Conduction Mode (DCM) and is running at 65 kHz switching frequency. It has a one output voltage with secondary side control regulation. The ICE3RBR0665JZ is the latest version of the CoolSET™. Besides having the basic features of the CoolSET™ such as Active Burst Mode, propagation delay compensation, soft gate drive, auto restart protection for serious fault (Vcc over voltage protection, Vcc under voltage protection, over temperature, over-load, open loop and short opto-coupler), 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 auto-restart enable, etc.
Summary of Features
650V avalanche rugged CoolMOS™ with built-in Start-up Cell
Active burst mode for lowest standby power
Fast load jump response in active burst mode
65kHz internally fixed switching frequency
Auto restart protection mode for overload, open loop, VCC under voltage, over temperature & over voltage
Built-in soft start
Built-in blanking window with extendable blanking time for short duration high current
External auto-restart enable pin
Max duty cycle 75%
Overall tolerance of current limiting < ±5%
Internal PWM Leading Edge Blanking
BiCMOS technology provide wide VCC range
Built-in Frequency jitter and soft driving for low EMI
Benefits
- Best in class low standby power
- Good EMI performance
Potential Applications
It is especially suitable for small power supply such as DVD player, set-top box, game console, charger and auxiliary power of high power system, etc
