SRK2000DTR ST AC-DC Controllers

The SRK2000DTR is a synchronous rectification controller for DC-DC converters from STMicroelectronics in SOIC-8 surface-mount package, designed to control N-channel MOSFETs for secondary side rectification . For selection, verify supply from 4.5V to 32V after turn-on, turn-on threshold of 4.5V typical, turn-off threshold of 4.25V typical, operating supply current of 35mA at 300kHz, quiescent current of 150µA when disabled, and operating temperature from -25°C to +125°C . Features include adaptive driving algorithm for maximum efficiency, programmable turn-off threshold via external resistor, and undervoltage lockout protection . Ideal for high-efficiency DC-DC converters, AC-DC adapters, battery chargers, LED drivers, and any flyback or forward converter requiring synchronous rectification to reduce conduction losses and improve efficiency.
