SRK2001TR High-Efficiency Synchronous Buck Converter
The SRK2001TR, a compact synchronous buck converter by Renesas Electronics, is engineered for high-efficiency DC-DC power conversion in space-constrained applications. Operating from a 4.5V to 18V input range, it delivers a fixed 3.3V output with up to 2A continuous current, leveraging integrated high-side and low-side MOSFETs to achieve peak efficiency of 95%. The device employs a frequency-selectable switching architecture (200kHz–2.2MHz), enabling designers to optimize trade-offs between efficiency and component size. Key features include soft-start circuitry to minimize inrush current, thermal shutdown protection, and under-voltage lockout (UVLO) for robust operation. Its compact DFN package with a 0.5mm pitch supports dense PCB layouts, while its low quiescent current (28µA) makes it ideal for battery-powered systems. The SRK2001TR also integrates cycle-by-cycle current limiting and hiccup-mode short-circuit protection, ensuring reliability in fault conditions.
