The STMicroelectronics SRK2001LTR is an advanced synchronous rectification controller specifically designed for Switch Mode Power Supplies (SMPS) applications. This high-performance device is tailored to enhance the efficiency of secondary side rectification in flyback, forward, and half-bridge converters with output voltages ranging from 5 V to 24 V.
The SRK2001LTR integrates a sophisticated control system that precisely regulates the timing of the external MOSFET to minimize power losses and increase overall efficiency. It achieves this by monitoring the voltage across the MOSFET and turning it on as soon as the diode would start conducting, and turning it off just before the current goes negative.
Key Features
- Adaptive turn-off logic to optimize efficiency across a wide range of load conditions
- High noise immunity and propagation delay compensation to ensure reliable operation
- Support for high-frequency operation, making it suitable for modern, compact power supplies
- Low quiescent current to reduce standby power consumption
