STMicroelectronics Power Supply Controllers, Monitors SRK2001LTR

The SRK2001LTR is an adaptive synchronous rectification controller designed specifically for LLC resonant converters. It features a dual gate driver for N-channel MOSFETs, with adaptive turn-off logic and turn-on logic that incorporates an adaptive masking time. The device operates within a voltage range of 4.5 V to 32 V and has a low quiescent current of 50 OºA, making it suitable for applications requiring low power consumption in light-load conditions. This controller includes high voltage drain-to-source Kelvin sensing for each synchronous rectifier MOSFET, ensuring efficient operation with a total turn-off delay of 35 ns. It also provides protection against current reversal and manages load transients effectively. The SRK2001LTR is packaged in a compact SSOP10 format and is compatible with standard level MOSFETs, making it a versatile choice for various applications, including AC-DC adapters, all-in-one PCs, high-end flat panel TVs, and industrial SMPS.
