Off-Line SMPS Current Mode Controller with integrated 800V CoolMOS® and Startup cell (brownout & frequency jitter) in DIP-7 PG-DIP7 Features • 800V avalanche rugged CoolMOS® with Startup Cell • Active Burst Mode for lowest Standby Power • Selectable entry and exit burst mode level • 100kHz internally fixed switching frequency with jittering feature • Auto Restart Protection for Over load, Open Loop, VCC Under voltage & Over voltage and Over temperature • External auto-restart enable pin • Over temperature protection with 50°C hysteresis • Built-in 10ms Soft Start • Built-in 20ms and extendable blanking time for short duration peak power • Propagation delay compensation for both maximum load and burst mode • Adjustable brownout feature • Overall tolerance of Current Limiting < ±5% • BiCMOS technology for low power consumption and wide VCC voltage range • Soft gate drive with 50W turn on resistor Description The ICE3AR2280JZ (CoolSET® -F3R80) is an enhanced 800V MOSFET version of ICE3BRxx65J (CoolSET® -F3R 650V) in DIP-7 package. The PWM controller is based on F3R 650V with some new and enhanced features. In particular it is a device running at 100KHz, implemented with brownout features, installing 800V CoolMOS® with startup cell and packaged into DIP-7. It targets for the low power SMPS with increased MOSFET voltage margin requirement such as Off-Line battery adapters, DVD R/W, DVD Combi, Blue ray, set top box, auxiliary power supply for PC and server, etc. In summary, the CoolSET® F3R80 provides good voltage margin of MOSFET, lowest standby power, selectable burst level, reduced output ripple during burst mode, reliable output with brownout feature, accurate maximum power control for both maximum power and burst power, low EMI with frequency jittering and soft gate drive, built-in and flexible protections, etc. Therefore, CoolSET® F3R80 is a Product Highlights • 800V avalanche rugged CoolMOS® with startup cell • Active Burst Mode to reach the lowest Standby Power <100mW • Selectable entry and exit burst mode level • Adjustable blanking Window for high load jumps • Frequency jitter and soft driving for low EMI • Adjustable brownout feature • Auto Restart protection for over load, over temperature, over voltage and external protection enable function • Pb-free lead plating; RoHS compliant
