Introduction
JW5033T is a current-mode monolithic step-down voltage converter. It operates over an input voltage range of 3.7V to 18V, delivering 2A continuous output current through two integrated N-channel MOSFETs. Under light-load conditions, the regulator operates at reduced frequency to maintain high efficiency and minimize output ripple. The JW5033T ensures robustness through short-circuit protection, thermal protection, current runaway protection, and input undervoltage lockout. The device is available in a 6-pin TSOT23-6 package, requiring minimal external components for a compact solution.
Features
- 3.7V to 18V input range, 2A output current
- Up to 95% efficiency
- High efficiency at light load
- Fixed 800kHz switching frequency
- Input undervoltage lockout
- Inrush current control protection
- Overcurrent protection with hiccup mode
- Thermal protection
- TSOT23-6 package
Applications
- Distributed power systems
- Network systems
- FPGA, DSP, ASIC power supplies
- Green electronics/appliances
- Notebook computers
