1 / 10 page  eorex (Preliminary) EP3102 Nov. 2006 www.eorex.com 1/10 150 KHz, 2A Asynchronous Step-down Converter Features • 3.3V, 5V, 12V and Adjustable Output Version • Adjustable Version Output Voltage Range, 1.23V to 37V +4% Max over Line and Load Condition • Input Voltage Range up to 40V • Output Load Current: 2A • 150 KHz Fixed Frequency Internal Oscillator • Voltage Mode Non-synchronous PWM Control • Thermal-shutdown and Current-limit Protection • ON/OFF Shutdown Control Input • Low Power Standby Mode • Built-in Switching Transistor on Chip • SOP-8L package Applications • Simple High-efficiency Step-down (Buck) Regulator • Efficient Pre-regulator for Linear Regulators • On-card Switching Regulators • Positive to Negative Converter • Battery Charger Description The EP3102 is a monolithic integrated circuit that provide all the active functions for a step-down switching regulator, capable of driving a 2A load without additional transistor component. Requiring a minimum number of external component, the board space can be saved easily. The external shutdown function can be controlled by TTL logic level and then come into standby mode. The internal compensation makes feedback control have good line and load regulation without external design. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. The EP3102 operates at a switching frequency of 150KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed +4% tolerance on output voltage under specified input voltage and output load conditions, and +15% on the oscillator frequency. The output version included fixed 3.3V, 5V, 12V, and an adjustable type. The package is available in a standard 8-lead SOP8. Typical Application |
